Some won’t be persuaded, some will. Plus, when there’s a bunch of people in a room, there’s a collective will to find consensus and be liked. People who didn’t reason themselves into their position will move their views closer to that of the collective to be more comfortable. At the same time, if they are being banned and restricted, there’s an instinctual will to fight back. E.g. if someone is angry at me or hostile towards me, it almost doesn’t matter if I agree with them, I’m likely to oppose them.
