I think you are right that here it's not the proper audience for this.
I really like many of his videos discussing science and atheism and that stuff, but his crusade against the feminist movement (part of it) and against atheism+ and Anita are a little too much.
I understand his disbelief about the threats against Anita but again accuse the supposedly victim for not behave as he would do it's very dangerous.
Now I do believe that followers of Anita and people whom hate him might organize his ban and that makes a lot of sense. For me the bann in the tweeter account is baseless and unfair independently of the opinion you might have about him.
