There is a difference between individual subs having such rules and a sitewide implementation.  Subs have these rules to keep discussion on topic however the site as a whole has no reason to do this so long as content is not illegal.  As has been said many times since the move over here, we may not agree with places like r/coontown, in fact I find that place utterly reprehensible and such views popping up on FPH swiftly brought in the banhammer but who are we to stop them on their own sub? As we say to the obeasts, if you don't like it don't go in those subs.
