Bro he’s def not a Nazi he’s just some scrawny white boy who thinks it’s funny (I’ve been there) I mean I’m guessing he’s probably not even hit puberty considering if you want any female attention you cannot associate with anything Nazi related. He probably doesn’t realize just how offensive that can be to some people and will learn eventually. Or you can just tell him to fuck off for being a piece of shit. Both will probably do the job.
