I don't even get how that's gonna work. Inevitably, he'll work alongside/under/oversee Jewish colleagues. That'll be an awkward Hangouts meeting. "Oh hey there's the guy that thinks I'm violent, I wonder if he'll judge my work/team interaction impartially..."
Most are almost never put in a position where things they've done or said over a decade ago is put under a spotlight. You have to be in a specific position, and have people specific want to take you down in the first place. Why do you think this specific post from 14 years ago happens to have been brought up now?
But if Google thought he was now benign, wouldn't he just remain at the post? Moving him to a different department seems to indicate that Google think he did wrong, but not that much wrong as to fire him. I'm not sure how to reconcile that.
It's just a bad look specifically for the head of DEI, who's whole job is to promote diversity. If it was any other position they probably wouldn't have cared.
"If you're going to work with other people, some of them will probably at some time possibly, or you might even know about, something bad they said that might apply to you."
At that point the question is how that gets worked out. If the other person has since apologized, and it was a long time ago, then I don't think it's too much to ask that other folks maintain a professional relationship / work with such people.
