You can really come off as racist sometimes, a culture racist.
A culture racist? Ugh. Your skin is thinner than your vocabulary.
The word you’re looking for is ethnocentrist, and if you had the slightest clue, you’d realize that I’m actually more of a cultural relativist.
I’m also an asshole, but since it’s easier for you to get offended than it is to get educated, you can’t tell the difference.
