What I'm getting from u is that ur not aware of any laissez-faire environments unless the state has atheism as the official religion. In contrast, I'm not aware of any government w/ atheism being the state religion w/o extreme totalitarianism. My other thought is you'd be absolutely apposed to any suggestion from me of any place where the general population is theist and is at the same time egalitarian and open.
So it seems we're stuck.
Atheism isn't a religion.. so I repeat, which countries are you talking about?
