Sorry guys, but I have some difficulty with both your statement's. First, most Muslims are not radical or fundamental. These are the over the top, strap a bomb to your body, beat your :-? because of a picnic extremist. I have met many muslims while working in healthcare and I can tell you they are generally nice people. Although I find any muslim to be to extreme in their belief, not all are going to try and kill you.
Second, we have a number of extremist in our own country. Do you remember any of the abortion clinic bombing's? Who were behind those? What about some of the white supremist beliefs? Ever see image's a cross being burnt.
Finally, why does it matter how many muslims there are in the world, just because so many believe in something doesn't make it a good thing.
Only playing devils advocate...
No pun intended...
