I wouldn’t call it a slur. To the extent it’s an effective insult, it’s due to centuries of behavior by white men. If someone uses “white man” to call out certain behavior, it might be worth their target considering why they got called out. Maybe sometimes it’s unfair to the white man to be called out, but often it isn’t. For folks who find it troublesome or disturbing to not receive the benefit of the doubt about their intentions as a white man, consider how much benefit of the doubt is given in everyday contexts to pretty much any individual who is not a white man.
Aren't you worried about the consequences of supporting generalizations over a group from the actions of their members? I learned at an early age that that's not OK, but it seems to be changing again, as long as the target is in a specific group.
