Good old Earl and his charming little ideas that only Islam is only the sum of its BEST parts. If a Muslim does something bad, said Muslim is magically kicked out of Earl's definition of Islam and they cease being Muslim.
Have you isolated yourself so much from the real world that you have never met a good person who was religious?
Come to think of it, some of the most decent people I have ever met have been religious.
Take a deep breathe, pack your gun if you need that, and go outside and visit a Church or a Mosque or a Temple sometime and talk to some people.
Most of those people are there because of the people next to them, not the Pope or Billy Graham.
There's a saying *take what you need and leave the rest*
