Christian nationalists say that other people shouldn't watch porn but that they've figured out a curious caveat within the faith that exempts them, personally. Then they establish special repositories of pornographic material that serve as an incentive for membership and a form of blackmail against turncoats.

Porn becomes a more direct means of patriarchal control - both in how it restricts which senior members are allowed to buy it and (in turn) which women are allowed to sell it, and at what price. It is a form of societal monopsony intended to make sex work a privilege afforded to elites at below market rates.

They all have Sunday brain. Living one life Sunday morning that's just disconnected from their choices they make the rest of the week.

But, that's indoctrination for you. The most infuriating part is when otherwise good & great people decide that calling themselves Christian, setting themselves up as human shields for all the abusive controlling monsters among their number. They'll say the monster is 'a sinner' and 'doesn't represent our values' while rushing to the defense of Christianity. They'd rather white-wash the Christian label than fix the structural abuse done by by 'their neighbors' (but it's never their church that's the problem).

They're usually (usually) not the same individuals, but the evil ones deliberately use the "good" ones as a shield. They're a happy to rally as Christians to any attack from outside the religion, but will write off abuses they see internally as "not my church".
