You know, very often, if you look at the kinds of communications that they're getting in an ISIS recruiting video, the videos that, you know, that one hears of as radicalizing them, these are like action movies. And so in the sense, it's that by closing off the idea that young Muslims and particularly young Muslim men can be American heroes, it increases the chance that they'll try to be some other kind of hero.
