Final answer:
No credible evidence supports claims that Martin Luther King Jr. had illegitimate children; discussions of his contributions to civil rights are more relevant.
Step-by-step explanation:
There is no factual or historical evidence to support the assertion that Martin Luther King Jr. had illegitimate children. Discussions surrounding the personal lives of historical figures, especially allegations of this nature, can often be speculative and controversial rather than factual. When assessing the character and impact of Martin Luther King Jr., it is more common to focus on his substantial contributions to the civil rights movement, nonviolent activism, and his significant role in the advancement of racial equality in the United States.
