I’d say that deciding that question isn’t that important (as described, fine, don’t ban WorldStarHipHop). Rather, I’d zoom out and ask whether a society where poor people brawl for income is a healthy one, and maybe think of some alternatives to do that would be better.
Also were these Kenyans all screened for mental illness, or is this a crack a few eggs situation?
