The solution to speech you don’t like is more speech. This is the system working as intended. Free speech does not mean freedom from social consequences for expressing unpopular opinions.
This isnt more speech, its saying shut up or find out, its an attempt at mob justice, one makes websites with disregard for privacy and truth (did they say it or just associated to the organisation like the old student?), one amplifies the identified people with a truck, the other intimidates with death threats, and none feel very guilty because each carry through a fraction of the whole ordeal. More speech is great, but thats a romanticised view you have, because these people are putting themselves above the law.
There’s also an easy solution. You can very publicly state that you don’t agree with the group that you were once part of. But this is saying you should be able to make a heinous statement and then walk back it when you get confronted about it.
What do you mean by "tolerate" here? You don't have to support their views. But they should absolutely be allowed to speak. In a society that values free speech, we often have to tolerate speech we don't like.
