They are fanatical in their beliefs and many live inside a bubble of not just media, but it makes up a big part of their social life, in many ways rightwing fanaticism centered around abortion has supplanted actual Christianity for many of them. Even then the Southern Baptist roots and theology of evangelicals is bullshit, a religion of slave owners and bigots. Be an asshole all you want, hate brown people, because your thoughts, words and deeds count for nothing, you get into to heaven by blind faith alone.
