The Average American's take on Evangelical

"UnChristian" (authored by David Kinnaman and Gabe Lyons from the Barna folks), Do we project that we are only "against things" and never "for anything". According to the book's research, the majority (was the figure 87%? I forget) of non-believers thought that "Evangelical" was the name of a political party and had no idea it had any relationship to anything spiritual.
