I think there are a lot of threads that come together that amount to capital's exploitation of women for unpaid social reproduction as a source of surplus value. I don't think chuds like explicitly have a list like this but they have internalized these concepts ideologically to the point that it doesn't need to be explicit (although if pushed sometimes they will admit it):

1. Bourgeois ideology is the primary ideology, and bourgeois symbols of wealth are aspirational goals for petty bourg and workers by default.
2. The forced exploitation of women requires buy-in from women. We know religious trad wives exist, I have some in my family. Some large percentage of women have to be made to fear society and hence desire to be "taken care of" (owned) by a man which is again bourgeois as the wives of the bourg are exploiters, not exploited.
3. Whiteness is the "highest value" race, when value is the product of an unconscious process of comparison
4. The bourgeoisie promises a woman to do domestic work in the home if a man will work hard enough to "provide" for her and their children.

So basically the obsession with white women is the false promise of a "high value" house servant/prostitute to the petty bourg, ideologically committed or naive, aspirational and reactionary workers, anti social and hyper exploited and backward men.

Like so many people have said, its about making women into property but more specifically turning women into capital that produces value for its owner, as well as carry out the crucial labor of social reproduction for free or at hyper-exploited wages
