“You must be fun at parties.” Uh why would I want to party with Nazis?
“So edgy.” If I cared what liberals thought, I wouldn’t be a communist.
“You’re just a larper.” Larp it till you make it, am I right? Also, what have larpers ever done to you?
“Nazism and communism are the same.” Yes, Nazism is when you want to destroy Nazism forever rather than fund it the way you do.
You could also just argue with them that Democrats aren't even remotely 'good' anyways.
