These are just crazy heads, they fuck it up for every organization (read: Islamic terrorists, hyper conservative evangelicals, etc). I can't promise you, mop bashery is not part of the Good Book. But, it makes for a great clip.
The most extreme elements of an organization are usually the definition of said organization, to those with little knowledge of the true ideology of the organization. I see it on CNN and Fox, it's a fault of rhetoric.Its not partisan, I mean. Religions are full of rhetoric, same.principles apply. Jesus was the best rhetorician that has walked the Earth, it would be dishonest to deny this.
