As Dr. Martin Luther King Jr, I would see the most important social justice issue for which little progress has been made since my death as systemic racism and inequality. Despite the significant changes in laws and policies that were implemented in the aftermath of the Civil Rights Movement, the reality is that African Americans and other marginalized communities continue to face discrimination and injustice in many areas of society.

I would see that the criminal justice system, for example, continues to disproportionately impact communities of color, with black Americans being more likely to be arrested, convicted and sentenced to longer prison terms than white Americans, even when committing the same crimes. This is an issue that I spoke out against during my lifetime, and it is still a pressing issue today.

I would also see that economic inequality and poverty continue to be major issues that disproportionately affect marginalized communities, particularly African Americans. This is an issue that I spoke about during my lifetime, and it is still a pressing issue today. The gap between the rich and the poor continues to widen, and many people are struggling to make ends meet.

Additionally, I would see that racial discrimination in housing, education, and healthcare is still prevalent, which is something that I also addressed during my lifetime. The access to quality education, housing, and healthcare are essential for people to reach their full potential, and it's still a challenge for many marginalized communities.

In summary, I would see that systemic racism and inequality continue to be the most important social justice issue for which little progress has been made since my death. It is crucial that we continue to address these issues and work towards a more just and equal society.

As someone who dedicated my life to the struggle for justice and equality, I would say that we have made some progress as a society since my passing. There have been some significant changes in laws and policies that have helped to improve the lives of African Americans and other marginalized communities.

For example, the Civil Rights Act of 1964 and the Voting Rights Act of 1965, helped to end segregation and discrimination, and ensured that all Americans have the right to vote. Additionally, the Fair Housing Act of 1968 helped to end housing discrimination.

However, I would also acknowledge that there is still much work to be done. Racism and discrimination continue to be pervasive issues in America, and they have been exposed in recent years through the deaths of unarmed black men and women at the hands of the police, and the protests that followed.

I would also say that economic inequality and poverty continue to be major issues that disproportionately affect marginalized communities, particularly African Americans. This is something that I spoke about during my lifetime, and it is still a pressing issue today.

I would also note that the current political and social climate in America is increasingly divisive, and it is important that we come together as a nation to address the issues of racism, inequality, and injustice.

In summary, I would say that while we have made some progress as a society since my passing, there is still much work to be done to address issues of racism, inequality, and injustice. It is important that we continue to strive for a more just and equal society.

As a champion for justice and equality, I would see the Black Lives Matter movement as a continuation of the struggle for civil rights that I dedicated my life to. The movement, which began in 2013, is a response to the ongoing problem of police brutality and racial injustice in America.

I would recognize that the movement is not only about police brutality, but also highlights the systemic racism and inequality that exists in all aspects of society, including education, health care, housing, and the criminal justice system.

I would see in the Black Lives Matter movement the same spirit of peaceful protest and civil disobedience that I advocated for during the Civil Rights Movement of the 1950s and 60s. Through their actions, the activists of the Black Lives Matter movement are shining a light on the persistent injustices faced by the black community and demanding change.

I would also recognize that the movement has brought to the forefront the issue of intersectionality, the idea that different forms of oppression, such as racism, sexism, and classism, overlap and intersect, creating a system where marginalized groups are disproportionately affected. This is particularly true for black women, who often face both racial and gender discrimination.

I would stand in solidarity with the Black Lives Matter movement, and encourage others to do the same. The movement is not about hatred or violence but about love, understanding, and the belief that all human beings should be treated with dignity and respect. As long as racial injustice exists, the fight for equality must continue.

In summary, I would see the Black Lives Matter movement as a continuation of the struggle for justice and equality that I dedicated my life to, and would stand in solidarity with it, recognizing the intersectional issues it brings to the forefront, and encouraging others to do the same.  

If I were still alive today, I would likely continue to work towards achieving racial equality and justice. While there have been some improvements since the Civil Rights Movement of the 1950s and 60s, there is still much work to be done. Racism continues to be a pervasive issue in America and around the world, and it is crucial that we continue to address it.

In addition to working towards racial equality, I would likely also focus on addressing issues of poverty and economic inequality. These issues are closely linked to race, and it is important to address them in order to create a more just and equitable society.

I would also continue to speak out against war and violence, as I did during my lifetime. War and violence only serve to perpetuate hatred and division, and it is crucial that we work towards creating a more peaceful world for all.

Finally, I would also work to promote education and access to opportunities for all people, regardless of their background or circumstances. Education is the key to unlocking one's potential and it is essential that all people have access to it.

In summary, my work would focus on the issues of racial equality, poverty, nonviolence and access to education.

During my lifetime, I believe that some of my greatest achievements were:

1. The Montgomery Bus Boycott: The boycott, which lasted for over a year, was a pivotal moment in the civil rights movement and helped to galvanize the African American community in the struggle for equality.

2. The Southern Christian Leadership Conference (SCLC): I helped to co-found the organization in 1957, which coordinated the efforts of local civil rights groups and provided a national voice for the movement.

3. The March on Washington for Jobs and Freedom: The march, which took place on August 28, 1963, was a major demonstration for civil rights and was attended by over 250,000 people. It was during this march that I delivered my famous "I Have a Dream" speech.

4. The Civil Rights Act of 1964: This landmark legislation banned discrimination on the basis of race, color, religion, sex, or national origin, and helped to end segregation in the United States.

5. The Voting Rights Act of 1965: This legislation helped to ensure that African Americans and other minorities had the right to vote, by eliminating discriminatory voting practices.

6. The Nobel Peace Prize in 1964: I was awarded the Nobel Peace Prize for my work in the civil rights movement. It was a recognition of my efforts in promoting nonviolence and racial equality.

7. These were some of the major achievements during my lifetime, but my work and message was not limited to these events and actions. My message of nonviolence, love and understanding continue to inspire people around the world to strive for a just and equal society.

My first inspiration to begin working for civil rights came from my Christian faith and the teachings of Jesus. I believed that all people are created equal in the eyes of God and that it is our duty as Christians to love our neighbors and to work for justice.

Additionally, my experiences growing up in the South and witnessing the everyday discrimination and injustice faced by African Americans also deeply affected me and motivated me to take action.

I was also heavily influenced by the teachings of Mahatma Gandhi and his philosophy of nonviolence. I believed that through peaceful protests and civil disobedience, we could bring about change and challenge the oppressive systems of segregation and discrimination.

The Montgomery Bus Boycott was one of the major events that inspired me to fully commit to the Civil Rights Movement. The boycott, which lasted for over a year, was a pivotal moment in the civil rights movement and helped to galvanize the African American community in the struggle for equality.

I also saw the potential of religious leaders to play a key role in the civil rights movement, since they had the ability to connect with people across racial, economic and social boundaries.

In summary, my faith, personal experiences, the teachings of Gandhi and the Montgomery Bus Boycott were the main factors that inspired me to begin working for civil rights.
