Yes, sadly I too have noticed this behavior from Glenn, his tone quickly turns confrontational at times and this starts to pick at his credibility in the view of the audience.
Someone should really explain this to him so he can make some corrective efforts on this.
It's the outfit. If he looked like Spider Jerusalem everyone would be fine but he looks like a congressman so people expect more politesse than they get.
I guess it's too much to expect Julian Assange levels of stagecraft from everybody.
I saw an interview with him and the BBC a few weeks ago. When the subject of the UK came up he said he didn't care what they thought and he didn't care if he couldn't enter that country ever again because of what he believes is a hostile political system.
He seems very willing to make enemies of entire countries which is an odd personality trait to say the least. I would think most westerners would be extremely distraught if, for some reason, they realised they could no longer visit the USA, UK, and numerous other major Western nations because of something they had done wrong.
