You can only “list” examples of political correctness that make (in some way) sense to you, but increasingly PC is in the mind of perpetually aggrieved people who completely ignore reality and try to force those around them to walk on eggshells. It does take creativity to step outside of yourself and to try to see things from the perspective of others, that’s just being polite. I think though, that PC crosses back and forth between good manners and a sort of societal co-dependency. In extreme case it is exactly like being married to some sort of substance abuser or drunk with all the arbitrary rules and punishments for made up infractions.
They sow a majority of people in a society with inborn guilt(being a male for example.) They force these people to atone for it. Not once. They continually arbitrarily invent new instance of infraction which those people atone for. They want to always keep them in short leash. They want to control your attitude, taste, and thinking.
Rule No. 1 to break yourself free: Do not feel guilty.
