That’s genuinely hilarious. It’s so hyperbolic and dripping with contempt I can hear the user finish it out loud with, “you stupid motherfucker.”
It really does mimic the childish and catastrophic language used by rationalists. Wish there was a good word for it.
I bet there is a German compound one.
Childishandcatastropiclanguageusedbyrationalists doesn’t have that ring to it.
I feel like you would use an extended modifier instead: Die kindische und katastrophale von Rationalisten gebrauchte Sprache. Or maybe something like “die kindische und katastrophale Rationalistensprache”. Not sure though. This is pushing the limits of my B1 German though.
