I don't think we should be banning anyone. I'm very pro-free speech. I'm not a Conservative or a trumper. I'm a limey brit.
But I don't quite think I'd go as far as you have in the above quote. I think Trumps continued lies and the support of multiple other republicans encouraged and legitimised these actions.
Does that excuse the actions? No.
Does it make them criminally liable? Imho, maybe. Incitement is a thing.
But they certainly can't say "it's not my fault people listened to me". There is a very real need right now for republicans to look at the company they've kept for the last 4 years and do some soul searching.
That would be best for them and for the country even if I don't think failing to do some merits arrest or deplatforming.
This isn't a right/left spat. It's a moral fiber, truth vs lies question. What sort of person does a party member want to be and to be associated with?
