"No religion promotes terrorism?"
You're mistaken on that. Though maybe the word "terrorism" is not used in the Qu'ran, it's there. When Allah gives his followers permission (and even commandment) to kill unbelievers, I think that constitutes terrorism. And don't start telling me that I'm taking all those verses out of context. Hundreds of verses in your book promote violence.
Also, the billions of Muslims who do not actively participate in terrorism are still helping to promote it---by giving their time, money, and manpower to organizations that carry out terrorism. I don't think Islam can hide it's ugly head anymore...we all have eyes, ears, and brains.
