Partially yes. It took a while to work out what was going on because we were comparmentalised. Many regrets there
I like to use an analogy of the soap box individuals in Cambridge city centre in the 1990s as an analogy. Back then you could go and listen, interact with them and heckle them if you wanted. There was mutual respect between the hecklers and the soap box folk. In fact we mostly drank in the same pubs afterwards and had a laugh and some serious discussions as well.
But now the platform allows the soap box hecklers to flick away people who challenge them. For example if we take Anthony Steele's channel he spent a long time heavily moderating the comments in response. This feature, implemented to get rid of the odd dickhead, leaves a monocultural echo chamber which is counter to the point of challenging ideas. All opposing discussion is removed. Followers form pockets of subscriptions and bad ideas (demonstrably) tend to amplify leading to all sorts of hell breaking loose.
Thus at the end of the day, someone has to take an executive decision on deplatforming eventually but far too late. So ideally yes challenging them is a good idea (you'll find me challenging Anthony Steele's content repetitively until he deletes my comments) and is effective it's no good if the person you are challenging can evict the hecklers silently from the crowd.
The same is true of Question Time here in the UK and some of the screen time the BBC have given to balancing crackpottery without moderation. It leads to amplification. Then we have no choice but to deplatform.
Just a point on the family members, there was an incident where he actually caused harm to protect someone (my sister) from something irrational. I won't go into that here but stripping their rights is exactly what we do to people when we put them in prison for causing harm.
Edit: to add this is still way better than it used to be with moderated press and television being the only communication channels. But it's a long way from ideal yet.
