I honestly can't imagine thinking this is what one wants to do with their time. Like, I accept that I can't understand this sort of racism and such, but like, even if I was a bigot I can't imagine deciding that what I'm going to do with one of my afternoons is drive around threatening a child's birthday party.
But also, it amazes me that white Americans manage to feel aggrieved by black Americans even today. We're the ones who keep fucking them over not the other way around.
