MWD definition of bigot: a person who is obstinately or intolerantly devoted to his or her own opinions and prejudices; especially : one who regards or treats the members of a group (such as a racial or ethnic group) with hatred and intolerance
Note that in the definition, race and ethnic group are listed as examples. There is no exception that permits mistreating ethnic groups because you "don't like them" or you think "your prejudices are based in science and everyone else's prejudices are based in pseudo science."
