This is the entire problem with you “rationality” lot. You think rationality is something easy and obvious—and this simplemindedness lets you rationalize all your prejudices and stupidities.
You make “rationality” an idol, and cease to be able to reason, because you’re all terrified where actual thinking might lead you.
Clowns LARPing at “fighting Nazis” while acting like Brownshirts is funny and pathetic.
You are funny in the same way, railing irrationally at irrationality, thinking you're fighting the thing you actually are.
