Is this you? Why?

This morning I read the USA Today headline: Most religious groups in USA have lost ground, survey finds. Interesting.  Surely there are poorly managed denominations, others that believe strange things, still others that have storied histories.

Then, I was browsing on Drudge and I found the following article: More Americans Losing Religion. Embedded there was this:

Fifteen percent of respondents said they had no religion, an increase from 14.2 percent in 2001 and 8.2 percent in 1990, according to the American Religious Identification Survey.


Why would it be true that fewer people are religious?  Is this you?  Why?
