Too much attention is given to right wing evangelicals. They do not represent Protestants in general. A Pew poll I saw reported that only 11% of evangelicals identify as strongly conservative, and even for those, the connection between religion and politics is weak.

There are a few high-profile televangelists and a few colleges and churches such as the Bob Jones University that are utilized by the media to stir up fear and disgust, but in general, protestants are not much different than the general population. The Southern Baptist Convention, which is the largest evangelical group, has, in fact, adopted a number of very liberal resolutions.

I am not totally convinced that the root of the religious right is a desire for racial segregation. Whether true or not, it is a moot issue now. It makes good ammo for smearage purposes I guess.
