How do i deal with someone that thinks im stupid

This maybe considered a hostile work envirnoment. I would warn them verbal not with anger. Kill them with kindness. Then if that didn't work I would speak to my boss. And, tell your boss you don't appreciate the hostile work envirnoment your co-workers are creating. You just want to do your job not get involved in work politics. If that doesn't work talk to a lawyer about discrimination. Good Luck.
