I'm reminded again that if a username or profile has as its label some expression of violence toward an entire class of people, whether that's an out-group or in-group, or simply an other-group, engagement is likely to be unproductive.
I DO get the frustration and history. #PunchingUp *IS* often justified.
Cases in which that extends to advocacy of violence should be very limited and strategic. I'm not saying "never", but do think a few times before doing that.
