Well, OK, here goes:
I don't fully agree with the last three bits before he says "Church, YOU are the problem" -- he basically said that people were NOT leaving the church because:
- the culture is perverse and beyond help
- people are chasing money, sex, and material things
- gays, Muslims, atheists, and pop stars have "screwed up" the common man's morality
Take the middle one; certainly, some people leave churches because they want to "make a living", and they want to devote their time to being successful and not to being in church. They promise themselves that when they "make it", they will get back into church (but that's just a trap, and they never do). Paul wrote about Demas leaving him, because he "loved this present world". It does happen.
I don't have as much problem with #1 and #3; I don't think that these are reasons why people leave a church. I think American culture has gone downhill, but that may not be true of every nation. The message of the Bible is does not belong to any one nation or race or economic class. The Bible predicts a great apostasy, and we are seeing that today. It really is true that Jesus is coming back, and signs are all there. Noah talked about "rain" for over 100 years, but it happened. I see the lack of morality, but it is following the path the the Scriptures tell us.
He then lists his real reasons in the article. My thoughts about them:
1. Cannot really speak to this, as we don't do a "show" -- in fact, we try to avoid making Sunday an entertainment
2. Not fully explained as to what "church talk" is unhelpful - there are some people who enjoy learning doctrine; others may not care as much.
3. As I understand this point, he wants churches to co-operate with other groups in the community more instead of being insular. There are issues with this point for those that believe in separation.
4. Fighting over trivial matters, he says. That sounds like the ecumenical teaching to make more and more items of faith "non-essential" so that larger groups can co-operate. What new evangelicalism has shown is that completely bankrupts faith, leaving no essentials at all.
