i am technically an atheist, but not a political atheist like yardley. i just choose to believe the more scientific origins based on my geological and science studies through undergrad and grad school coupled with my readings of current science journals etc.. i call myself a christian because that was how i was raised and how my family around me believes, and in some social circles they automatically pen me with the yardley types and its just not worth getting into the details in most social situations. i do display a "darwin fish" on my truck, so no one can claim i hide my beliefs.
similar with obama. i think he is technically a muslim but knows he has to hide it if he is going to succeed and be accepted by mainstream america. he has known this all along. he has been following his grand plan, from "community organizer" to present.
so he attended rev wrights church, got married in the church, etc etc. that doesnt make him a christian anymore that sitting in your garage all day makes you a buick.
