None of us is perfect - all of us have our own weaknesses and demons. Some shout racist slogans, other insult players' families, even to the extent of mocking serious illnesses, others make clear their wishes that players legs get broken. Which is worse? It's all bad to me - there's no difference - and I say this as a black person.
But I can tell you what disturbs me more. Not what offends me, but what disturbs me, and that's the insults to players and their families. If I were a player, I would much rather monkey chants than some of the other disgusting stuff I've heard from the stands. But that's just me - to each his own. Let's hope that one day fans don't feel the need to hate and insult opposing teams and players.
