Punishment is still due. Without remorse, punishment should be doubled.
So who gets to decide the punishment and under what authority? Patrick? You? Someone "objective"? theymos?
You decide. I'll be happy with that.
If you want theymos to ban Phin, then you need to take your arguments in favour of that to theymos.
Ban is stupid. I never support censorship.
(I'm convinced Phin has a script in his head about how these things are going to play out when he does them and is utterly unable to understand why they don't play out as expected).
He needs to shut himself up. Gun to the head was one fair and reasonable option.
