I think he might have meant "political correctness" less in the sense of "extreme sensitivity about denigrating homosexuals" and more in the sense of "arbitrary rules of social etiquette that people get extremely upset at you for violating".
"Political correctness is a right-wing term used when they want to call somebody X, but may face social consequences for doing so."
He thinks terms like 'political correctness' and 'victim culture' are some sort of right-wing slurs for virtuous attributes. He doesn't seem to be aware that this notion doesn't exist for 90%+ of the world's population.
To him, it’s insane that a white person could care about a non-white; or a straight could care about a queer. He thinks that’s fake.
It’s sad, but it’s a peek inside the mind of a shitty human being who had abhorrent parents.
Only in the West do they lose their mind defending the honor of people who are not in their in-group. I'm not sure if that is honorable, or just idiotic.
