This is true.
Kevin MacDonald fmaously described Judaism as a "group evolutionary strategy" (characterized by a high degree of endogamy and a resistance to genetic and cultural assimilation). This is partly wrong Jews as have the highest intermarry rate of all groups.
However, in a way ALL "tribal" groups that are formed around national, racial, social, ideological, economical, political, religious identity markers are MALE group evolutionary strategies. It is MEN who come together and form tribes, aiming for in-group altruism and hostility towards out groups.
Women -no matter if they're Jewish or goy- are essentially AMORAL when it comes to these male "tribes", which is why they were always listed along with cattle and prisoners of wars in early tribal texts such as the (((Bible))).
In French-occupied Rhineland after World War 1, German women fucked French soldiers, many of them being black, left and right. Once the occupation ended, these women were shamed and attacked as traitors by German men. Later, in Nazi-occupied France, French women fucked German soldiers everywhere. Once THIS occupation ended, these women had their heads shaved and were paraded through the streets as a punishment for collaborating with the enemy. IOnce US and Soviet troops were occupying Germany and Austria after World War II, these Aryan women now fucked Russian and American soldiers en masse. They just want to fuck the winner, they are creatures without fatherland just like the monopolized capitalism of today that is destroying the nation state is.
There is probably nothing more bluepilled than the idea of redpilling women. In 1984, George Orwell already noted that "It was always the women, and above all the young ones, who were the most bigoted adherents of the Party, the swallowers of slogans, the amateur spies and nosers-out of unorthodoxy."
