He didn't just wash off his hands. When asked in an interview about a moderator who edited a trans user's profile to intentionally misgendering them (yup, even that's not off limits for their mods), he justified it saying that 'It's not like using the N-word or something'. (For context, the n-word itself was innocuous. It gained notoriety due to its misuse by bigots like this).
There are several such examples - repeatedly even after being called out. I don't belong to any diversity groups. But I don't care if they make the world's best operating system. I will stay well away from it if only to avoid any interaction with such a group. They're a bit too happy about harassing people (not just transgenders either).
It's not really that baffling. What was done to the Jews by the Nazis is utterly indefensible. And some of the attitude that led to it still persists in society. The Zionists used that to guilt trip the world into banning public criticisms against Jews and Israel - legitimate or otherwise. They use it to silence even the ultraconservative Jewish sects and actual Holocaust survivors who speak up against the transgressions within their community. This was particularly effective in Germany as they were coming to terms with what they had done.
This is why we should never encourage victimhood narratives by anyone. They're very often trying to emulate the atrocities they describe. Hate speech should be condemned and called out - but uniformly without discrimination.
