I have never read any of what he's said so take this with a grain of salt.......But I can understand why he might seem weird about shutting down conversations and such......These internet type discussions can go so many different ways and are easily manipulated without you ever even knowing it. They also tend to quickly escalate and degrade. He's probably trying to keep his opinion as the only one being heard and the "message" being the one he wants to be put out.....without any background noise to distract from his gig nd how he does things
