You all do know, the Nineteen and under age group make up the majority of people throughout the Middle-East, right?
and it was that age group that started the last revolution in Iran.
the concern is not about Muslims. the concern is about Islamists. almost all revolutions through history have been started by well intentioned people seeking some form of "freedom". almost all of them have ended up with totalitarian governments, and repressed freedoms. those well intentioned people who started the revolutions are either co-opted or killed.
Iran is a pretty good example. while the history is complicated, it's safe to say the the Shaw didn't do a hot job. on the other hand, the general population in Iran had far more freedom and opportunity than they do now. the majority of the Shaws oppression was directed at the islamists and also at political opponents....often one in the same. so they had a revolution. they wanted freedom. what did they get? they got an Islamists government that was more oppressive than the one they overthrew.
same thing happened in Russia, Cuba, Vietnam, and China. it's less about religion than looking at who has the most organization. you can pretty much bet on who will be in power after the revolution by looking at who has the best machine before.
probably a lot of Metallica fans in the more free areas of the middle east and asia. how many will there be after an islamist government takes over?
