I lived it when I lived in West Oakland. Tagging, violence, hell a neighbor was shot in the face in front of her family over a gang beef. I'm still exposed to it now working with people reentering society after being incarcerated.

You haven't been paying attention for the last 30 years, perhaps because you only circulate with people just like you in insulated echo chambers. I can tell you from having lived it: tags are not funsies and diversity and inclusion. They are male-cat-pissmarks-on-the-wall from gang members establishing, defending, and expanding turf, and they are unwelcome for very good reason.
