The term 'moderate Muslim' is an oxymoron.
I don't agree with that. A director with the company I work for is Muslim. He does't go to the mosque. Doesn't worship. Really, the only thing he does is avoid pork etc. He's 52 years old and has been in this country for 25 years. He's not a threat in any way.
He has two kids who are in highschool. Who knows if one of them will become a threat in the next few years? That's where the danger is.
