It's like trying to ban poor taste.I think it's all about context; each situation judged accordingly.
A blanket ban would kinda feel like a continuation of America's retards pulling down statues.
Honestly I wouldn't imagine anyone getting upset by this until now, but it's good foresight to avert any future situations where something isn't done in good fun, like an avatar with only a swastika or the symbol for planned parenthood.
This instance seems geared more to the tongue in cheek 'all in good' fun category.
Good luck.
You'd be better off trying to delete the internet.
