Yes, Islam is a peaceful religion; that part you have correct. Regarding EVERYONE KNOWING Muslims committed the murders on 911, well, I think the jury is still out on that one. I'll wait for the final verdict if you don't mind.
OH, Yes, Osama is a terrorist and he's getting exactly what he deserves. But he is just one person; just one piece of a puzzle that may contain thousands of pieces, and those pieces might turn up in some embarassing places.
They already have. Saudi Arabia, Egypt, mosques in the USA, (many clerics have scurried back to the ME) - mosques in Europe, over 80 Islamic orgs. in the Michigan area alone.
Embarassing, indeed.
