re: Somebody enlighten my privileged white arse on why #AllLivesMatter is racist

I understand your point. But don't you think that the statement "black lives matter" to a white person has some weird underlying assumption that the white person somehow thinks "black lives don't matter"? I mean , isn't at least a little insulting, in that it assumed that the white person needs to be reminded and lectured that black lives matter?

Particularly in light of outrageous black on black homicide and crazy disregard for black life by blacks? Personally, I'd feel better if instead of lecturing white people with an inane slogan that white people already agree with, if black people repeated it like a mantra under their breath before they went out on the street and killed each the approximately 9000 times they kill one another each year.
