AOG, there was no sensible debate. And in fact as I indicated earlier, this was possibly partly the fault of the interviewer.
Basically, Tommy Robinson's stance is this:
There's an issue with extremism in Islam: fair enough most people would agree.
However, the "powers that be" i.e. politicians, the police etc, aren't doing anything about it - in fact they seem to be on "their side". The implication therefore is clear (and was in fact born out by the film of one of his speeches): we will take the law into our own hands if need be. He may say he hates Nazis, but those are effectively the tactics of Nazis/Fascists. The thing is though, because of the way the interviewer approaches it, we never hear these beliefs thoroughly examined. It's left to others to do the analysis.
