Ah yes, "evolutionary psychology". The favorite field of behavioral determinists who observe some behavior in extant society, and instead of simply saying "this is how people are behaving, interesting, huh" they invoke a non-falsifiable hypothesis based on a pop-culture understanding of evolution to argue that such behavior is "in-built" in humans to fit their preferred political agendas. ("this is how people are behaving, and see I can come up with a theory that sounds convincing so that I can tell everyone this is how people are meant to behave).
