I am a new atheist having read all the current Athiest manafesto's.
I vote for Democrats and laugh when people tell me how conservative they are. Usually they only mean religous conservative not socially or intellectually conservative.
I have 2 kids in private school, live in the suburbs, married for 15 years, my wife's parents and mine have been married over 50 yeard each, and I'm the liberal. (ha!)
