BHEFA is an acronym for "bible-humping evangelical/fundamentalist asshat" This refers to the people in the spiritual right. This is is comprised of a few parts: "bible-humping" refers to the love of the Bible by these people. If you value it much, you may as well get all the way. The evangelical/fundamentalist component will pay heed on difference between an evangelical and a fundamentalist, which make up the religious right. Eventually, an asshat is an insult talking about somebody who's head is stuck up their butt. This reflects the spiritual right's denial of this modern world.
