The conclusion in this article by Joel McDurmon is as upsetting as it is true. I quote from it below:
"Thus the pietists who comprise the vast majority of evangelical and conservative Christians keep biblical law out of government, and stifle and condemn those who try. The pietists run interference, and the humanists follow the pietists’ blocking scheme for the easy touchdowns. (Admittedly, this sports analogy assumes there are actually some of these pietist Christians on the field. Most are actually on the sidelines or not even in uniform.)"
