I don't think it's that people have changed their beliefs so much, it's more that they are no longer afraid to tell you they don't have have such crazy believes like when they drink wine in church it is transformed into blood just before they swallow it. So why aren't people so afraid any more to tell what they truly believe? Because there are more people like that around them and, crucially they KNOW there are more people like that around them. It's not about what you believe, it's about what you believe other people believe. Depends on whose asking. A good development I would say.
