I agree with you that that’s all what gets labels as PC actually is. As you probably know, it’s perceived by conservatives as something else, an unfair limitation on their right to say whatever the hell they want. More extreme rejection consists of an insistence that un-PC beliefs are fine to think, say, and act upon because they’re (supposedly) true. The concept of PC also gets wielded by political operatives and opportunists in different ways. These days, it’s often used to claim (ironically) the mantle of victimhood – criticism of obnoxious or injurious speech commonly gets branded, ridiculously, as censorship by “PC liberals.”
