Well, when an argument devolves to "you're right but you're an asshole for being so" there isn't really anywhere else to go. I disagree that I'm an asshole, and yes I say things like "all lives matter". I do not agree that black people need some kind of global social movement promoting anti-white/male discrimination to help them, especially given that many of us live in places with no history of slavery and very small black populations. Even in the UK, only 3% of the population is black and in other parts of Europe it's far less still.

But even if we just focus on the USA, the situation and causes of some parts of the black population's outcomes are so complex that reducing it to "white people don't care enough" just doesn't make sense. White men don't make black men get divorced at a much higher rate, to pick just one example.

Greatest adversity I've faced "as a white male"? I ignored the question because it makes no sense to me. I don't know what it means, grammatically. I've faced all sorts of adversities and was a white male whilst those things were happening but that's not what you mean is it? How about being incorrectly accused of being racist? That's happened a couple of times. Whether that happened "as a white male" I cannot say, but I really doubt it would have happened had I been black. But then maybe it would have been. Who can know?
