I agree @BlessedKali
I've listened to a lot of JP and I've never ever thought 'what a wanker, he's totally wrong there'. But when I speak to friends about him, it's as though we are speaking about two different people.
The common complaint is that he 'uses a lot of words to sound intelligent but actually isn't'.
I don't get that sense listening to him. I feel like he chooses his words extremely carefully (watch his interview with Cathy Newman for example). I don't see the blurriness in what he's saying, ever.
