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.
