Why do you feel Christianity is dying off among white Americans?
Because a LOT of churches replace authentic spirituality with political activism and a perpetual victim complex. Many Protestant pastors preach about nothing but the end of the world and how everyone who isn't like them will burn in the fires of hell. Many Catholic parishes are about being anti-abortion, anti-gay marriage, anti-secularization and anti-euthanasia, with some Eucharistic Adoration, Rosary clubs and discussions of Mary's supposed messages at Fatima and Medjugorje sprinkled on top. Many Orthodox parishes (as embarrassed as I am to admit this) are more cultural clubs than actual Orthodox parishes--they focus more on being Greek, Russian, Romanian, whatever, as opposed to being ORTHODOX. I'm sorry, but when your family has been in this country for 3 generations and even the old people are fluent in English, it's time to switch the language of the Liturgy over to the language of the country you're in.
People have seen the intolerance of the Religious Right and how vociferously it is defended by all major Christian groups. People have seen LGBT children ostracized from families. People have been abused by parents and families, where these same families go to church and sit in a pew on Sunday and think themselves righteous and justified in continuing to abuse their own children. People have seen the spiritual collapse of much of American Christianity into just another political camp with the veneer of the Gospel stretched and twisted overtop. People are leaving the churches in America because the churches in America aren't teaching and living what the Gospel says we should.
What group do you expect will become the most prevalent? Why?
Atheists and agnostics, for all the reasons you cited from your article. Even those who believe that there is a "god" of some sort will feel no need to seek an organized religion, for the reasons I cited above, but they'll simply take from whatever religious tradition gives them inspiration and come up with their own individualized brand of spirituality.
With the young group of Muslims and Hindus, do you expect these religions to become a majority as the young people age and older folk die off? Why or why not?
I don't expect the Muslims to become a majority, unless we start letting in a whole lot more Muslim immigrants. Islam doesn't seem to spread too terribly far outside of the ethnic borders that it came here with, and any non-Muslim who converts probably has a video of their testimony on YouTube. The Muslims are like us Orthodox Christians: We're a cultural oddity, generally seen as too far removed from "Western" society for consideration by your average American. Cultural barriers are strong, even concerning religions which (theoretically) don't have them.
Will the unaffiliated become the majority? Why or why not?
I think they will be within the next 10 years. 20, tops. People are too fed up with organized religion as it chooses to exist now. That, and our current intellectual culture leaves no room for the spiritual. In an age where we explain literally everything through science, and anything unknown is simply something more for science to discover, belief in the spiritual or the divine is seen as just another silly superstition which will one day be disproven by science. (Even though science cannot disprove things not belonging to the observable universe, but whatever.)
Will Christianity ever rebound among white Americans in with its current values? If not, what values need to change?
I think it can, but there needs to be a serious reorientation.
1:
Focus on the Gospel. Everybody loves Jesus. Be more like Jesus. Do what He tells you to. Gandhi once said "I like your Christ, but I do not like your Christians. You Christians are so unlike your Christ." We should focus on making that sentiment a forgotten memory.
2:
Give up the stupid culture war. Christianity lost. Get over it. We're back to where we were vis-a-vis society in the 1st through early 4th centuries AD--a sideculture/subculture (which is incidentally where we grew the most, the fastest).
3:
Give up on trying to play politics. Church and state were separated for a reason. Originally, this was intended for the good of the Church. Acknowledge this and move on. You can inform your churchgoers about good, Christian morals, but don't endorse political candidates or parties. Inform the people and let them decide which foot they want to shoot themselves in. No party is perfect according to Christian morals. If there was a perfect party, that would mean that it's a Christian party, and somebody should tell them that Jesus' kingdom is not of this world, and it's not our job to make it be of this world.
4:
Get some community service going. Start up recycling programs. Start up food banks, host workshops open to the public for things like life skills and staying safe, start day cares, litter removal, disaster relief, visit the shut-ins, visit retirement homes, help out Habitat for Humanity, host blood drives, visit hospitals...
5:
Figure out how to share your faith without being annoying about it. Campus preachers and their ilk only serve to make Christianity look like a hateful freakshow circus. When it comes to the Church, not all publicity is good publicity.
6:
Teach your faith to your children yourself. So many people walk away from Christianity without hardly knowing any of what any of it was actually about. Catholics who go through years and years of religious ed don't know answers to basic questions about their faith. God knows a lot of Evangelicals only know about who the Antichrist is and what Pastor Joe said the Book of Revelation means. Religious ed can only do so much. So, it's the job of the parents to be informed about their own faith, and to answer the questions that their kids have, and to
be models of what being a good Christian looks like for your children. Which brings me to my next point...
7:
Live your faith outside of going to church on Sunday. I think a lot of people walk away from Christianity because they see it doesn't make any real impact on the lives of those who supposedly believe in and practice it. Parents should teach their faith to their children, not just rely on a Sunday school teacher to do everything for them. Read the Bible at home. Pray every day. Do some of that community service I talked about. Practice what Jesus did and preached. For God's sake, at least
try to be a halfway-decent Christian every day of the week.

This guy hits the rest of it pretty well I think.
