Deplatforming isn’t censorship, it is publishers saying they find said speech to be garbage. I don’t typically stop arguing someone because I have convinced them of my view but because I guess further interaction with them on the topic is a waste of energy. I am confident in all my arguments but a lot of people are too dumb and too emotional to be worth debating. And in the group context, arguing without moderation has mostly devolved into name calling and child porn. It is an experiment often repeated. Some people want a different experience, which seems to mean they want moderation in exchange for a good forum, e.g. this web site.
