I'm neither a free-speach maximalist, not a Trump supporter - on the contrary, I would say I'm pretty far left-wing. And that is exactly why I feel pretty ambivalent about this. Because what if next time there is a BLM demonstration in front of the Capitol, or for any other progessive issue? What if things get worse here, and we need a democracy movement / "peaceful revolution" like in east Europe? Then I might find myself on the other side of the ban.
I have the theory that we never really defeated fascism in western society. But mass media limited what you could say in public and so we kept a lid on it. Imagine someone disputing an election or calling for violence in the New York Times or on prime time TV. But with the internet and social media, this control function fell away. As a society we are realizing how problematic this can be and slowly reinstating the limitations that we had before the internet.
This silences the violent, the racist, and the extreme right-wing-nuts, but it can also silence progressive ideas and marginalized voices if we are not careful.
Right now we are moving to a situation where people like Trump cannot speak on the common public forum (putting the lid on them), but they can cause a lot of damage. I'd rather have the opposite situation, where they can rant as much as they want, but the society is so strong and principled that they cannot cause damage. But we are far from that, so I guess the pragmatic solution is to put the lid back on for now...
