I'm going to make racist, homophobic, and ableist jokes with my friends in private.
Why do you feel the need to do that?
They're fun and I can get away with it.
You shouldn't joke or make fun of those with disabilites. It could be you one day. Have fun with friends but do it without hurting others.
Relax I'm joking and it's just a joke.
Even if your friends laugh at jokes like that, most people don't find them funny and may be privately offended. There are plenty of funny jokes that don't involve putting down marginalized people. Try to be more creative and you won't need to mock the disabled or minorities in order to get a laugh.
