Simply put, they have no idea what they’re talking about.

Stalin took credit for defeating Nazis (after carving up Poland with them first, but who cares about minor historical details)

As I read that, it occurs, perhaps because they simply are not cognizant of, and do not cognise, any other way (e.g. any "freedom respecting" way), only their one true way. Why won't we just obey? And they keep their totalitarianising level of authoritarianism preventing them from entertaining the ideas, instead only seeing other ideas as threats, and only study them as far as they need to construct the next argument to protect the one true way, that they've identified with, and so defend as if their lives (and more) depend on it, obliterating critical, considerate, creative cognition, leaving only social dominance reflex mode....

... could be something like that.
