That's a major aspect of what's going on now: it's an internecine intifada.
Muslim versus Muslim.
Many of those in the streets are indeed youthful idealists yearning for democracy and liberty, but they're dupes because they're fighting alongside the jihadists who would be worse than there current oppressors. (MORE ON ONE PROMINENT JIHADIST TAKING AN EVER MORE PROMINENT ROLE IN EGYPT'S INTIFADA HERE.)
The authoritarian regimes they are rightfully angry with are not as bad as the jihadist regimes which will likely take their place.
It's as likely in Egypt as it was in Iran.
WHY DO MUSLIMS REJECT DEMOCRACY AND PLURALISM AND THE SECULAR STATE?
It's the Islam, stupid!
Their ULTIMATE oppressor is Islam itself - which, in the form that is most compatible with the Koran and the Hadiths and the Sura and with the life of Mohamed, is incompatible with secular pluralistic non-misogynistic democracy. IOW: Osama bin Laden is correct: only apostate Muslims can be good, modernist democrats.
That's why I now believe that Muslim youths must be first converted away from Islam before democracy can take root.
I used to think Islam would be changed as Muslims became more democratized, but Turkey proves that isn't likely. Desirable but not likely.
I am praying that the idealistic youths yearning for liberty will focus more attention and outrage on the jihadists in their midst, and less on the USA or Israel or their authoritarian oppressors.
Until they do, I shall remain a pessimist about the chances for real democracy in the Muslim world.
The biggest oppressor in their lives is Islam. Until they recognize that I feel that no real revolution can occur.
Until then there will continue to be lots of internecine killing.
REMEMBER: More Muslims have been killed by other Muslims than by anyone else.
REMEMBER: More humans have been killed by Islam than any other ideology - including all forms of socialism.
IT'S THE ISLAM, STUPID!
