Remember that bill that would strip non-profit status from any group, based on the whim of the president? With no hope of appeal? That was very popular with Democrats, until Trump won.

Even if you assholes don't abuse something like that, you know that you aren't going to be in office forever? There's an election every 4 years, remember?

Don't go conflating Democrats with the left, though. There's some overlap, but they aren't the same.

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]).

I am genuinely curious about your perspective—when you say the left can act in a fascist manner, could you provide some specific examples of what you mean? Also, how do you personally define fascism in this context?

Tell me you don't know what fascism is without actually saying it.
