Surely you don't really believe that of the 1,297 white people lynched, all were innocent. His point remains then, there is no shortage of guilty white men getting lynched in American history. Lots of white murderers and rapists got lynched, sometimes after they were convicted in court, by mobs who were impatient or particularly enraged.
So what is special to mean here? Uncommon as to be noteworthy? Based on what data?
It is also worth pointing out you assume the man is guilty and deserving of death, but this is arbitrary lynching. Even our most heinous deserve their day in court. Innocent until proven guilty is more than a multiple choice test answer.
I'm pretty sure that's the first time I responded to you, but whatever... If you concede that it's not unique, what makes you think it's special? I don't feel as though you are making a good faith effort to express your ideas clearly, and are instead choosing to nitpick the precision with which people paraphrase your argument.
