you're not expecting me to believe they're just joking, are you? they're edgy because their views are edgy and going out of style, so they're lashing out
Eh, personally I think it's between the extremes of "they're just trolling" and "they really believe it." Usually this sort of "edgy humor" is an exaggeration of their actual beliefs (because normal people wouldn't be alright with advocating gassing the Jews, even jokingly). It's like people that post national socialist memes - they may not literally be national socialists, but it's quite likely that they hold strong right-wing beliefs.
