No, I was joking about the bait, kind of a “you’re making it too easy,” but I don’t mind when people say “found the vegan” to me. What follows is longer than intended because I hyper focused on it.

Tl;dr: I take that type of statement differently depending on the context, but I wasn’t trying to dismiss you.

I would also personally not mind if someone said “found the x” for anything that applies to me, unless it was inherently a negative thing or something I’m ashamed of, and I just assumed others were the same. Like, I’m an immigrant in Germany and I’d be pretty upset if someone responded to me speaking German and said “found the American,” but that’s because I put in a lot of work to lose my accent. If they said it after I showed up to an appointment fewer than ten minutes early, I’d understand that they were intending to insult me and I’d feel put off, even though I think five minutes early is perfectly fine.

For qualities I’m not ashamed of, I think of it either as neutral or as an affirmation that what I’m saying or doing is in line with who I am. If I were talking about how mind blowing it is to live in a 500 year old house and someone said “found the American,” I’d probably laugh and agree, and if they said that after I said something about wearing mismatched socks and not caring what people think, I’d feel positive that that’s a known stereotype about Americans.

I’m autistic though, so I might be the outlier. I also completely miss passive aggression most of the time, so maybe people actually do intend to insult me when they say that, but I think it’s silly to view those negatively, so I take it about the same as I do when my dad says a political position I support is communism- still a win in my book. I’m pretty happy with my interpretation, even if it’s wrong, lol.
