“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.
In my experience only good comeback to the 1st three is some variation of "Huh?"/ "What are you talking about?" and remaining absolutely stone-faced while the other person explains themselves.
Don't engage with silly bullshit, b/c it's exhausting and you end up seeming undignified/ owned.

energy
Seconded, especially if you're dealing with CHUDs and they're calling you a "woke femoid SJW bluepilled soyboy" or whatever their new meme insult is, play dumb or make fun of them for being so reliant on memes.
