You actually believe this is the case now? You are aware of the existence of subs like /r/cutefemalecorpses /r/rapingwomen /r/beatingwomen /r/coontown /r/holocaust /r/candidfashionpolice and the likes right? If the admins are pushing an agenda they're doing a horrible job at it.

Oh completely agreed here, mods have been asking for more tools to deal with their subs for a long time. But at the same time a lot of users run to /r/undelete or /r/subredditcancer or whatever when they get banned/shadowbanned because they believe it happened because of their 'opinion'.
