I'm 29 and only recently had a religious discussion with my parents. They were the type that would, year after year, say around xmas time or easter "we are going to go to church for the holidays" and it never happened. They were far from religious folk. Christmas and easter were just times for the family to get together. However, when we had the talk about religion, my mom got upset and said I was being rude and an ass. It turns out though, that she is somewhat of a deist. She believes in a higher power and not necessarily the judeo xtian god. My dad on the other hand, does believe in the bible and shit, just not overly so.
I think it has become the societal default position to believe in gawd (at least with the older generation. Our time is near), so when we say we don't, it comes as a shock.
It is what it is mate. Atheists shall soon take over the world. Just make sure to do your part and feast on as many xtian babies as possible to thin the herd.
