I feel Google cornered itself into this pickle. On the one hand they need to grow their pool of talent and make the non majority to feel comfortable --which makes those not in the majority feel they have more than average support from Management, who in turn turn a blind eye to anti-majority bashing.
On the other going above and beyond for underrepresented groups will eventually grate against the majority when they ham-fistedly overcorrect.
This engineer likely got a nice severance or will get his due in court. Seriously, you don't fire someone for having a non milquetoast opinion.
I mean, I expect this heavy handedness from a Walmart but not from a Google. There are other more finessed ways to get your corp culture disseminated.
Off topic, but not having a union allows Google to fire these offensive employees, unlike School districts who must retain people who grind their own little axes.
