My personal suspicion is that this person is kind of messing up the test by being a moderate in reality. This author may well consider themself anti-SJ, but I'd be pretty surprised if they were actually conservative rather than "99% on board"
I interpreted this as a non-SJ working too hard to make SJ sympathetic to their own non-SJ ears. SJ taken on its own terms isn't /supposed/ to sound sympathetic to an anti-SJ.
This is Scott
Lots of very distinctive phrases and shibboleths. Too many, too thick for someone using them naturally. Too thick for someone using them intentionally to fake a position.
This is someone oversignalling their true position.
