Ms. Nasreen is absolutely right. Just eliminating the fundamentalists will accomplish nothing. Because soon, that religion will just produce another crop of fundamentalists -- perhaps even more virulent and violent than the last. That is just the nature of religion. And that is true of all religions, not just islam. Christianity, Judaism, and other religions all produce their own variety of fundamentalists -- the true believers who demand that everyone else must follow their own vision of their particular religion.
If others refuse to comply, the fundamentalists take that as a personal knock on them and their religion. For them, religious freedom means only that they should be free to force their religion on others (even if those others want no part of it). Tolerance and true freedom are foreign concepts, which they don't understand at all. I'd like to think there's a cure to prevent fundamentalism from spring from religion, but I don't think there is. It's just the nature of the beast.
