For women I find it's almost always deep insecurity or an abusive, usually older boyfriend that pushes this shit. Case in point: Soph.Millennial/zoomer lolcows who happen to also be militant Catholics have always fascinated me. They seem to live in their own little pre-Vatican II world where it is completely normal to insist that everyone live by traditionalist dogma, and act bewildered when no one falls in line with them. In Alyssa's case, it's even stranger because not only was she not raised Catholic, she hasn't gone through any of the rites as far as I'm aware. A couple years ago she said she still needed to do RCIA (adult conversion to Catholicism) but who knows if she ever actually did.
I wonder what @Skylar Ittner is up to these days.
