The real version is the first guy says he won't bake a cake for a gay couple, which is shitty, but his right. Then the second guy comes along and says he wants to kill the first guy because nazis also wouldn't bake cakes for gay people, so the first guy must also be a nazi, and nazis all deserve to die, so this guy does too.
Then a rational person comes along and points out that both of them are being shitty and everyone loses their goddamned mind over it.
I dunno about you, my dude, but the only people I've seen fucked up by antifascists were not saying that they didn't want to bake a gay cake.
But I've seen the people who didn't want to bake a gay cake be called pieces of shit who should do better. And I think that's just called social consequences.
