Just got to call them as they are. Fascist is the only appropriate label for someone who believes they have the moral right to remove people from the political process because they deem them "inferior" in some manner, be it because of their race, ethnicity, religion, or because they fail a preferred ideological litmus test.
Anyone who engages in such behavior is anti-democratic, pro-authoritarian, and 100% all scum-bag all the time.
