White people denying that they’re racist is literal violence because all white people are racist . . .
What they're trying to do is set the stage to justify their initiation of physical violence as self defense.
Deny you're racist, that's literal violence, and I can punch or kick you in self defense.
Admit you're racist, and that's so horrible I can punch or kick you, because you deserve it. Oh, and it's self defense, too.
They haven't quite managed to figure out that when they initiate actual physical violence (as recognized by most sane people) there's a good chance they'll get a whole lot more back in return than they're comfortable with.
