Funny how it's only directed at certain people or certain topics though. Applied completely inequally.
Your point only makes sense if the humour is general. But nobody's hoping on national TV when a female athlete trips going "ha ha she got Ted bundy'd, omg absolutely raped ha!" see how disgusting and vile that sounds?
But you know "pound me in the ass prison" is a cult classic (I still like the overall movie) and nobody would have any problem with airing it on TV.
No point arguing with humans tho, our species is lame.
