What do you base this on? I agree about orthodox Jews, but even their secular elite seem to have a surprising number of children, and its extremely rare for Jews to date blacks. Interracial dating seems most common among poor and working class white women, and not many Jews fall under that category. They are the wealthiest group by far.

Unlike other whites, Jews are expected to actually increase in numbers in coming decades. I've even seen shitlib Jewish journalists talk about having kids and invoking some supposed relative who "survived" the Nazis(IE they lived during ww2). They see having kids as an act of revenge and see the demographic destruction of Europeans as being part of that revenge. Nevermind that far more Germans(and white Europeans) died in ww2 than Jews, even if their likely inflated death toll is believed. Even a Jewish incel could just go on a Jewish dating site and find some Jewish woman who wants to have kids in order to perpetuate the tribe and make their parents happy. Even the secular ones tend to be very conscious of this kind of thing. You dont see anything like that with whites.
