One of my favorite exchanges in the game is when you can identify yourself as an ultraliberal to Evrart. He simply doesn't entertain the idea. He finds the concept so stupid he just insults you and moves on.
"You're not an ultraliberal Harry. Get the fuck out of here."
He straight up just calls you a slur even, he calls you the R word, pretty sure its the only real world slur they bother with too outside of the flaubert misdirection.
Cunoesse says a few slurs if I remember right, but they're in Finnish. She says a few words that are sometimes used as slurs for gay people. I don't remember if they're censored though.
Half of Finnish words are swears centering around the word vittu though
