He does seem to have toned things down a bit since his infamous "non-Muslims live like animals" video.
Admittedly he does come across as a bit of a nutter there. Though it looks like he is addressing a mosque here, so is trying to persuade a group of muslims that violence is not the answer to any of their perceived grievances and that using their religion as an excuse for violence is wrong. It is religious elitism, but then all religions do this. They all believe that they are right and everyone else is wrong.
I thought that in his debate at the Oxford Union and at another with David Aaronovitch at the LSE, he makes a lot of good points which seem to cut through any stereotypes of islam. He always advocates for the mainstream and moderate people in his religion and helps to debunk a lot of the 'facts' and opinions that newspapers such as the Mail seem to regularly espouse against his religion.
Personally think Britain could do with a lot more reasonable, well educated and articulate advocates for Islam (to an extent like him) in the media. It would definitely help the massive fractures in society that exist because only the most extreme on both sides are represented in the media.
However, they love to roll out the nutters as it attracts more clicks, views, etc.
