> This is a person who could not care much about ideology until ideology reached his house and destroyed it

I think this is made all the more powerful by being imaginary: if there really was some organized group he'd at least have some way of knowing who’s in it or what they do. Since it’s basically a conspiracy theory driven by not wanting to consider what he could have done differently, there’s nothing falsifiable, he can find signs of it almost anywhere, and anyone who tries to talk him out of it is suddenly a traitor. Since his son was trans, there’s an entire preexisting opposition group all ready to provide reassurance any time his faith wavers, too.
