A quote from Herb Meyer via Am Thinker:
Let me put this as starkly as I can: What's going on today in our country isn't normal politics. In normal politics honorable people will disagree, sometimes fiercely, about how best to deal with the issues that confront us - national security, border control, healthcare, education, energy, the environment, and all the rest. What's going on today is a kind of domestic Cold War -- a seemingly endless standoff, with the occasional hard skirmish -- between those of us who see the US for what it really is, and those of us who are seeing the US through a prism. And remember, unlike real prisms these intellectual prisms -- or, if you prefer, these political prisms -- are invisible. If you're looking at the US through a political prism, you don't know you're seeing through a prism and you won't believe anyone who tries to tell you that you are.
This is why Americans who see our country and the world through a prism are impervious to facts.
Read the whole, excellent thing.
