A Muslim is a believer in or follower of Islam- Nothing more, nothing less.
The Muslim terrorists that you hear of are confused about their religion, just like many Christians are. I am an American currently living in the Middle East, and Muslims are about the nicest people anywhere.
They're religion is probably more strict than Christians, for any violence of ANY kind is extremely sinful.
Muslims do NOT live in a "stone age" like some people say. People live in regular houses, and drive cars like everyone else.
Christian: "YOU'RE MUSLIM SO THAT SOMEHOW MAKES YOU A BLOODTHIRSTY TERRORIST."
Muslim: "No, it all it means that I believe in Allah. Christians have been known to do suicide bombings in the US as well."
