You will forgive me then, if I think that "surrendering to McCarthyism" and "pretending liars who say fascism has no meaning are right" seems pretty counter-productive to me when opposing fascism.
Amazingly enough, there have been perhaps HUNDREDS of books written that cover the topic of what fascism is; I suggest you read one - literally any one of them. Because clearly your reading habits ended after they assigned you 1984 in middle school.
