Fascists in the original sense, Mussolini, didn't tolerate opposition.

I'm not sure about modern fascists, but US politics does look rather Kayfabe-y to me. Fake opposition, there for the purpose of being an opponent.

Of course then you get all the discourse about what even counts as fascism, and someone brings up that the origin of the word is the Roman "fasces" (bundle of sticks) and how that etymological root points to the concept of "strength through unity" which is also why the Lincoln memorial has Lincoln resting his hands on them[0] and why trade unions often use the "strength through unity" phrasing (and get annoyed/upset by the connection).
