It seems to center around virtue signaling. Those who participate the most seem to be indirectly involved and locked in an arms race to see who can be more indignant on behalf of those who might possibly take offense, when and if they exist. Its a bit insidious because usually there is some merit to the complaint (as in this case, the variable name was a bit embarrassing and should have been changed with little more than a self-conscious chuckle) but thanks to the cult of PC, everyone over-reacts.
