Quoting Trent W. Buck (trentbuck@gmail.com):
"Evangelical" is not a term Rick invented; Rick is using it in the well-understood sense as seen here:
https://en.wikipedia.org/wiki/Evangelical_Christian
This is a distinct meaning from "Christians who evangelize", in the same way that "Anglican" is not the same as "angular".
That Wikipedia page is useful for gleaning the interesting point that self-described 'evangelical Christians' in the USA (overwhelmingly concentrated in the Bible Belt, and in aggregate comprising about 25% of the USA population) are _doctrinally diverse_. As the page says, all they have in common _necessarily_ is the odd notion of being 'born again' and the core creed tenet of salvation by grace through faith. All the disturbing stuff about racist foundation, traces of cruel attitudes left over from the days of slavery, rejection of what British Christians tend to call 'Christian conscience' (social good works helping the poor and afflicted, etc.) is true of _some_ American evangelical Christians, but certainly does not extrapolate to the entire aggregate group, i.e., most certainly not 25% of the USA population. You'll note that this is the sort of problem I warned about. The upthread cited author implied that various things were shared among evangelical Christians in the former Southern Confederacy, but that is an obviously overbroad extension to _everyone_ there who self-applies that label characteristics that only some actually hold.
