Why is a atheist lifestyle nearly impossible in the USA?

[Pat Mustard]

I’m still puzzling over what is meant by ‘atheist lifestyle’. Bar going churching, I don’t imagine my lifestyle would be very different if I was a believer.

"Atheist lifestyle" means exercising atheist ideas... such as:
1) Where do you find your friends? 
2) What you do on sunday mornings instead of church
3) What you do when a theist blocks some service or product because it interferes with their religious ideas
4) Do you consider females at 2-3% of computer users at the library a problem with your Atheism?

1) Same way I do every night Pinky. By trying to take over the world! No seriously, just by joining groups, clubs, pubs &c that interest me.
2) Lie in, go to the shop, go for a walk, go for a spin out to somewhere like Gougane Barra. It all depends.
3) Over here people like that get the firm hand of the law across their cheeks.
4) Sorry I had a BSOD trying to comprehend this one. Please rephrase.
