I sat next to a guy who once complained that our new Pakistani CTO fired our black coworker for no reason (he was a top performer but was called “lazy”) and then proceeded to fire 3 Indians and only bring Pakistani candidates to the final round of interviews. He was called racist for pointing this out by HR (all white women) and he was the next person to be fired and replaced by a Pakistani developer.

Moral of the story being that unless you already have another job lined up you shouldn’t even question things like this publicly as it can cost you your job.
