This is from a column of Leonard Pitts, who is in our Sunday paper each week. I often appreciate and agree with his conclusions. Here is a link.
If you and I had an argument and I produced facts from an authoritative source to back me up, you couldn't just blow that off. You might try to undermine my facts, might counter with facts of your own, but you couldn't just pretend my facts had no weight or meaning.
To listen to talk radio, to watch TV pundits, to read a newspaper's online message board, is to realize that increasingly, we are a people estranged from critical thinking, divorced from logic, alienated from even objective truth. We admit no ideas that do not confirm us, hear no voices that do not echo us, sift out all information that does not validate what we wish to believe.
The fact that you refuse to acknowledge a wall does not change the fact that it's a wall.
And you shouldn't have to hit it to find that out.
