These threads are just sad. I don't know why the mods allow them. Free speech should be respected but it seems like every few weeks someone starts one of these "hey, why do black people do this or that..." threads and, as expected, it turns to all out war. I don't know how anyone could read these threads and be convinced there's any sort of constructive discussion taking place, or any learning opportunities. They're just platforms for people to vent their racist views.
I think it's possibly therapeutic by now. It's just as typical and boring at the same time. 99% of time they don't chill out in these neighborhoods anyway yet so "concern" about them.
