I'm happy enough with him having a permanent ban.
He did come across as very arrogant ("I know the TRUTH and I'm not going to look at what you think is true.") and debates were never actually a debate, just a matter of him stating his opinion and saying everyone else was wrong. I'm not fussed about his "personal attacks", I just saw them as an enormous weakness in his discussion skills.
He was unwilling to consider learning anything new because in his eyes he was already 100% right.
