> By deplatforming these people and driving them further underground and paranoid, we limit their ability to attract people through social media, for fear of exposure.

Do you have any evidence to support that statement? Would you expand on why you think so? I would estimate that by driving them more underground, you make them seem more cool in the eyes of angry teenagers. You also make them more radical because underground their opinions are not exposed to contradicting views. In my opinion, we should do exactly the opposite - we should give them platform to speak and oppose them. Isn't that what open society is about?
