Not Muslim, but I've seen his debates with Anjem Choudary. Vid related.
Obviously Choudary is a hothead, but as a non-Muslim, for all I know he could be kicking ass with scripture. These guys never sit down with their holy texts and really analyze shit.
It's always:
1) No, the Qu'ran doesn't say that
2) Woah, you're really misinterpreting that
