So basically, he's preaching to Muslims who already think like him and the portion of Jews who aren't secular as all get out. Granted, that's a significant portion of the population, but I don't see anyone else siding with him. Hell, I don't even expect many extremely theistic Muslims to side with him, considering how people who are that fanatical don't tend to play well with people of other faiths.
Honestly, I think this will do more harm than good to his cause. Almost every piece of circumstantial evidence I've seen suggests that trying this hard to demonize you opponents will only backfire, because people will inevitably realize you're full of shit when they see what the horrific boogeymen you've promised them are actually like.
