I think that these people who wouldn't vote if they couldn't vote for Stein are, simply put, stupid.
Trump attempted to overthow the American government on January 6th and has joked about becoming a dictator. There are many more things that he's guilty of, but these two things alone make him significantly worse than Harris, who, as far as I know, does not want to become a fascist dictator. Are you seriously trying to suggest that Trump is worse than Harris?
