From the link: In 2007, 60 percent of people who said they seldom or never attend religious services still identified themselves as part of a particular religious tradition. In 2012, that statistic fell to 50 percent, according to the Pew report. "Part of what's going on here is that the stigma associated with not being part of any religious community has declined," said John Green, a specialist in religion and politics at the University of Akron, who advised Pew on the survey. "In some parts of the country, there is still a stigma. But overall, it's not the way it used to be." I would have to agree with this.
