Why are muslims so violent?

Not all Muslims are bad. I believe you are referring to the violent terrorists groups (murderers). However, murdering comes from every walk of life in all shapes and colors. Now, with that being said, I am an American and I do not trust Any Muslims. Reason: How is one to tell the good from the bad. They go, live among you, go to work, have families etc fit right in and then boom a phone call and next thing you know they are killing Americans. I hate being this way, but the past and their words tell you otherwise. I am not willing to risk my life and/or my families in the hopes that this one is a good one. So for the one answer that said we made them that way, they made me that way too. If they came in my country they get everything, if I go to their country-will I make it out alive and unharmed? Last I checked they all HATE Americans.
