This is the fundamental issue with people arguing against free speech: I can never tell if they know they behave fascisticaly or not. Are they ignorant, or do they know?

People who support censorship always believe the censors will always side with their preferences. They never consider what happens when people they oppose control the censors, and for them merely not having allied censors in place feels like they are being silenced (see conservative Christian types who inevitably get angry any time Christian-focused language isn’t enforced [aka War on Christmas or anyone else requesting a display when there’s a public religious display on government property]).
