if we can be in offices now without regressive troglodytes in positions of authority freely making loud racist (and completely personalized) insults directed at their non-white peers and subordinates, to the guffaws of all the other men in the room (this is an actual thing I witnessed as a young intern at a defense contractor in the late 1980s, and no I was not the victim. to get a racist incident so glaring that even in 1988, it stays in the mind of a young white 18 year old kid for 40 years, means it had to be pretty bad), HR probably didn't ruin exactly everything.
