Just about all ethnicities, cultures, religions, etc have sick jokes about them. I remember in the 60s-70s one was on how many Jews can you fit in a VW Bug? 20, but all in the ashtray.
I also recall uses for a dead cat, babies in Le Machine, what do you call a guy with no arms & legs in the water? Bob. The disabled probably got more than their share.
So it’s nothing new, but still sick. Easy to say when you’re young, but hopefully most of us mature out of it.
Dark humor isn’t for everyone ...
