I don't see anything but a spurious correlation to something about who someone is and what they do for a living. A more accurate correlation to why evangelicals are in decline would be statistics based on beliefs like the fact LGBTQ acceptance is on the rise publicly. Personally I feel, anti-theism as a social movement has done a wonderful job redefining the term religious to mean closed-minded and irrational in social circles and that makes it less acceptable to be religious, thus making it less "in" to be a theist. A relationship between beliefs and beliefs or definitions would be far more convincing and less spurious to me.
"There ought to be a term that would designate those who actually follow the teachings of Jesus, since the word 'Christian' has been largely divorced from those teachings, and so polluted by fundamentalists that it has come to connote their polar opposite: intolerance, vindictive hatred, and bigotry." -- Philip Stater, Huffington Post
