This is very well stated. We all - especially those of us who never do - ought to watch Glen BECK once in a while so we see and hear what he is saying. Then, if we disagree, we ought to say something about to anyone who will listen.
The idea of so many people being so ignorant is really scary. There are huge numbers of people in the US whose views would frighten us, and we usually don't want to realize this, and we certainly don't want to be with them. But if we fail to listen, and answer bad speech with good, or at least inaccurate with truthful, I think more people win than if we pretend these people don't exist. They do.
