It’s easy: “Woke” and “political correctness” are words that are not really used by left-wing people. There are only a few lefties who would call themselves “woke” or who would advocate for “political correctness”. Those words, however, have been taken over by right-wing conservatives and are used broadly to bash the other side. So if somebody is using that like Paul Graham here is doing, you know that he has a right-wing-conservative world view. Just because using “woke” as a category is nothing somebody progressive left-wing would do.
