I honestly don't see why it matters, why care about what somebody believes in? If a religion has an honest set of values for a person to live by, theres no reason to argue, unless they're extremists. I think most people that would consider themself religious (speaking about Christians mostly, no idea about the rest of the world..) generally accept the changing values of society, well, from what I've seen personally. The only reason we make such a big deal most of the time is we remember the one or two people that argued with you, or we see on the news etc.. My mum was telling me the other day that many people later in life turn to religion, because its more comforting in older age, because it gives their life purpose and it also makes the prospect of death more comforting.
