Who, aside from racists, would find them funny?
The rest of us.
See, we already live in an enlightened society. We don't find racist, misogynistic, homophobic, or other bigoted speech acceptable.
We do however find racist, misogynistic, homophobic and other jokes funny. You forgot the disabled, jokes about the events in Tunisia on Friday and jokes about the bus crash in Belgium this morning.
It's called humour. Maybe you lack it, but you can go fuck yourself if you want the rest of us to abandon it.
