The thing with bullshit nutjobs like this bloke is, they consider moderate muslims their enemy, which is why they have no qualms about setting off a bomb in a crowded marketplace and killing other muslims.
if you want a bit of a background on the rise of militant islamism, check out a film called 'the power of nightmares' it basically details militant islam sees anyone harbouring any views which are less hardline as their own as the enemy, and fair game for attack.
it's also scary because one of their stated goals is to force divisiveness, and create an 'us or them' mentality among muslims here and abroad, which isn't hard when all the 'the west is at war with islam' claims are flying around.
