Will be interesting to see how Google handles other old examples of people writing things perceived to be offensive. Apple clearly has taken the opposite approach, with the firing of Antonio Garcia Martinez. While the google employee's comments are clearly anti Semitic, one can hope he has changed since then and give him another chance. We are too quick to condemn people for life due to their past mistakes. With that said though, a diversity role is probably not going to be an ideal spot for him going forward and re-assigning him is good.
Plenty of time... the totalitarian principle of QM notwithstanding, not everything not forbidden is compulsory at a macro level; academia is not a deterministic machine for yielding studies given the appearance of a phenomenon. Otherwise I'd ask you to provide some studies quantifying "plenty of time".
I feel 13 years should at least be producing nonfiction essays or something that passes for journalism. It took 4 years for 5000 trump books to come out. 13 years for the upending of racism towards being against the whites should be plenty, too.
Regarding Garcia Martinez, I am still surprised "straight male" is such a disadvantage that being POC doesn't buy enough oppression points to allow you to criticize white women. Then again, maybe it's more that being Hispanic specifically isn't enough. I have a hard time imagining a black man getting fired for the same comments.
