Imagine the outrage if some toothless redneck in Alabama somewhere developed a considerable following based on a reinterpretation of the Bible in which slavery were not just still legal, but more or less encouraged; where rape of any non-members of the church was encouraged; where they had death squads who routinely killed people who were not members of their faith, more or less randomly; and where they preached that one day they would rule America?
The enemy of my enemy is my friend. This is the creed of the Left, and based on their actual behavior, they consider their main enemies the United States, its history, and the people who in the main built and maintain it.
