Can a Good Muslim be a Good American?

Your friend would definitely not make a good American. There are many Wahhabi sect and others that are taught to believe some of the things you say from what I have been told. It does argue for the sane man to be suspicious. I have known many Muslims that are totally outstanding people and make very good citizens. It is usually pretty easy to see when people hold you in contempt and I have met a few Muslims like that in school. I would prefer if those types find a home elsewhere.
