That specific troon is Caronline Petit, who was trans before it was mainstream. He was also one of the original culture warriors, giving The Third Birthday a bad review because the attractive female lead was "a submissive sex object", and docked a point from GTA5 because misogyny.
From was I remember, Anita hired Petit after getting criticised for not pushing the whole trans thing as that movement started to gather steam. I think Petit left early because Anita stopped paying him. I wouldn't be surprised if Anita was a terf, but I don't think she's said anything about it.
