But I will note some statistics that should be concerning to the religious folks. Namely that people who have no religious affiliation (the 'nones') are seriously on the rise in the US:
To be fair, the US still lags the rest of the developed world on this measure. There are still some places that are more religious than America, but not anywhere I'd like to live. Africa, the middle east, and southeast Asia come to mind.
I sort of see the rising percentage of self identified nones as analogous to other long term trending statistics like vaccination rate, literacy rate, life expectancy, teen pregnancy rate, and violent crime. These stats tend to lag behind the types of measures we have previously used to measure a country's development, like access to indoor plumbing and electricity or per capita GDP, but they still mark progress. I'd like to see wealth inequality added to that list, but I think that one is centuries away still.
I think it's all part of the natural progression of societies. The pyramids were built by slaves who worshipped sun gods. Four thousand years later we have spaceships and internet, but have only recently taken a stand against slavery and we're still stuck with the sun gods and their modern derivatives. Eventually we'll drop those too as people realize that they just serve to support the same sort of power imbalance now that they did then. Freedom of information makes it pretty tough to keep thinking adults believing in the supernatural, so I expect that the coming century will see religions of the western world morph into cultural and historical institutions that celebrate their supernatural origins as traditions, not as facts. My kids still get presents from Santa, even though they know that reindeer can't really fly.
Judaism is already most of the way down this road. Most of the Jews I know are atheists, despite active involvement with their temples and traditions. They see it as a cultural identity and a celebration of their past, but they're not seriously preparing for the arrival of the son of god to walk among men. They recognize that their creation stories are historical embellishments that became myths, just like the Greek and Roman myths, the Egyptian myths, the Native American myths, and the Christian myths. Beautiful stories worth teaching and remembering, but not literally true.
it is my strong suspicion that the defection from mainline Christianity to Nones strongly parallels the increase in tolerance for things like gay marriage, and a more progressive world view in general.
Wow, that's a much more succinct way of saying the same thing I just spent three paragraphs on.
