I would encourage people to code switch rather than adhere to one style of language over another in every case. Imho, it’s kind of problematic that language itself has become racialized in America to the point where people can actually be criticized or made fun of for speaking in the “wrong” style associated with their perceived ethnic background.
I think you got hit hard by Poe’s Law here. Except it’s more like people couldn’t tell if you were jokingly or genuinely getting your math wrong… Even after you explained you were joking lol
