I'm new to this site and it seems to me that coming out as an Atheist in the USA is quite a big thing , I am English and nobody seems to care. My Mum who is a devout Christian one day said to me "Have you lost your faith son" I replied "I never really had any faith in the first place" she simply said that's alright son your still a good lad, and that was that. You've got to love her 86 she is.
The UK has always been more progressive than the States. There is a strong undercurrent that one can be any religion here. Really, Any Religion You Want. BUT FOR GOD'S SAKE, YOU CAN'T BE AN ATHEIST! (They're heathens)
I wonder how much diverse ethnicity creates this difference. In the US, the most segregated group are Caucasians, by choice. SMDH
