Islam is massive, over one billion people. It would be literally impossible to manipulate this huge 'religion' into a tool for terrorism unless the very basic tenets of mohamedism were sympathetic to the terrorists' cause. Terrorism stems from islam, which teaches hatred for the "infidel"; the two cannot reasonably be seperated, accept by the ignorant and the blind.
Right because millions of people have never been fooled or coerced into committing evil.
