I'm sure brigadiers factor into it, but a less comfortable truth is that there's a lot of internalized racism and class discrimination among the young white professionals who live in DC and frequent this subreddit - and discussions about police and homelessness tends to draw those attitudes out.

Unlearning internalized racism and class discrimination takes work - and there's no guarantee that people in this subreddit have done that work just because they live in D.C. or vote for progressive Democrats.
