> Fascism is but one particular flavor of malicious totalitarianism, and totalitarianism can coagulate around a vast variety of beliefs across the political/religious/cultural spectra.

I can go through a list like that, make sure that I check none of the boxes, and decide that I am verifiably not A Bad Person. (As if the only kinds of badness are fitting Eco's fascism checklist.) Or that the movement I'm attracted to is verifiably not A Bad Movement.

(All that said, it's not a totally bad list, and it does cross over some between different flavors of politics. Even Antifa checks more boxes than they would be comfortable with, if they seriously considered it.)
