I don't want to create conflict, but if you read biographies of MLK Jr.'s life - there was a dark side to that great man as well.

Just because a person's ancestors were abused does not mean they never did anything bad themselves. Here's a link that talks about plagiarism and infidelity: https://allthatsinteresting.com/martin-luther-king-dark-side

How factual is it? How credible? I don't know, honestly. I'm not an expert on his life and, like the others I mentioned, he was a great man. But even if the accusations above are false, he was not perfect because no one is perfect. Including me. So, if I am wrong and the accusations are false - please feel free to provide links that correct the record and I'll concede.
