This is in no way a defense of Elon. He is a horrible Nazi and he hates Jews and I'm a Jew.
That said, I'm not seeing where he brought up the Holocaust. He made a bunch of very offensive puns regarding Nazi leadership, but unless I missed it, nothing about the Holocaust. All the critical responses seem to mention it so maybe I'm missing it?
I guess I feel like "makes Holocaust jokes" is just unnecessary hyperbole when what he said was awful enough.
