Totally normal.

If I went into a Brazilian political forum and was super enthusiastic about telling the Brazilians who they should be voting for, and then after I made it sort of a part time job for a while, someone realized that I don’t speak Portuguese and asked hey what’s up with that, where are you from, and I said not, oh my wife is from Brazil so I’m into it, or yeah I moved here I’m living in Rio for the year for work but I haven’t learned, or none of your business why but yes it’s of interest to me, but HOW DARE YOU AD HOMINEM ME and receive it as an attack… yeah that would be super normal. Totally ordinary stuff.
