This has been one of my main theories since educating myself towards racial realism. I didn't know VDH thought so, although he had to boomerfy and republicuck it. For one, the church gets positively retconned into everything. There was no catholic breeding program. This is absolute nonsense as the elites and the rich bred more or less like Pagan kings and leaders. The church wanted the monopoly on sanctifying relationships and kinship. It might have resulted in some less ostensible demonstrations of fecundity. But certainly not from the White underclass who was always contend with a solid monogamous model. The church even made it easier to abandon your core family several times in history.

Secondly, we have this weird anti genetic notion that Greece somehow invented proto-boomer US values without seeding it biologically. This is pure leftism (culture over nurture) although the implications allow for breeding mechanisms (both detested by the left AND right). But how did those breeding patterns appear everywhere Whites go in history, be it Pagan or christian, without being majorly genetic? What would be the cultural vector from Greece towards Rome? Etruscan people were already individualistic farmers when Greece had it's heyday.

Individualistic core family units are a White trait. They are incredibly effective in pre urbanisation and a precursor to kingdoms and empires. Because they are so effective, elites try to control them as much as possible from all angles. They are our strong suit and our curse.
