"Moderate half"?? We wish...
And why is it when referring to 'Islam' the only catagories recognized are either 'radical' or 'moderate'? Isn't there a third and thus more innocuous "peace loving" version of Islam? If there indeed is, I would assume that percentage is miniscule.
It's pretty tough to speak out when the media isn't paying any attention to you, and especially hard when the bad guys have the guns and you don't. (Interesting note: England is beginning to understand what happens when the thugs have guns and the people don't)
We are learning that fact by what's happening in Iran right now with the students and the people finally beginning to stand up after 20 years under Islamic rule. If you get the opportunity, read some of the Iran List threads that have been posted here. You will find significant reason for hope.
