Interesting link. they do not allow for you to see racial breakdowns for the answer, but with black claims to higher religious affiliation and audacious epigone's splits from other surveys on religion, it is safe to say the big change recently is in whites. the affirmative answer has a dramatic drop after the '60s, but stays steady around 60% since. the interesting change is the change within the negative or unsure answer split. whereas in the past it was an even split amongst a firm no and an i don't know, the recent trend up is in no. this could be a hardening of irreligious whites, atheist comfort in expressing their views or simply a modern view of the complexity of modern times being unique. it isn't unique. another change might be in modern misunderstanding of religion combined with a fear of truly admitting what prime mover problems are.
The general environmental dysfunction that children grow up in. Divorce. Religion can't fix it in itself, but people who want to engage in a religious marriage with the idea of death until you part could solve that. Illegitimate children. That'd be an easier fix. Religion is like a k-selection enforcing structure. Drug and alcohol addiction. Empty souls and lack of coping skills will push people to substitute with numbing the pain through chemicals. There are more, but these are some that are the core of other dysfunctional behavior. Similar to the debate about macroeconomics being only built up from microeconomics or not, many of larger society's problems stem first from personal choice at the intimate level. It's why progressives will never fix anything since they never assign agency to idiots.
The core of these problems lie in people. Humans are animals with a soul or animals with the potential to be lights upon the earth. We still have deep brain desires and reactions. The problem lies in being fed a steady diet of be yourself, individual freedom, unrestrained individualism and anti-institutional restraint. When pundits speak of the possible libertarian moment, it is silly because we do live in it already. Neoliberalism or Washington Consensus economics favors winner take all economics with access to the government helping out. Individuals have all the unrestrained freedom of children with their behavior. Every deviancy is encouraged. The state provides a safety net for all problems, and all consequences are socialized. The steady stream of anti-organized religion propaganda is just a piece of the anti-family and anti-private organization messaging. Anything that can unite the people outside of the state's control and guidance is a problem to the state mandarins.
As long as the culture is attuned to non-religious answers and can smear religion at every turn, religion will not solve problems. Religion also needs the flock. Sure, the poz that has infested many Protestant churches has turned some people away but many people just do not want to go. What do they say, "It doesn't speak to me. It doesn't relate to me". Stop being a narcissus. Religion is not meant to speak to your petty 21st century, late Imperial American self. You either feel it or you won't. Our chattering class and punditocracy does not feel it any longer, and with that, our virtue is gone and religion does not stand a chance. It will not answer our problems because there is no environment in the current system that will give it a chance.
