And to be fair, some liberals. Perhaps those who study the human mind can help us here. There appear to be personality types who are completely convinced that they are right, end of story. My recent conversation with Les highlighted that. As much as he used the language of conciliation and dialogue, he never really entertained any other idea because he was already right.
The AP notes that Tom DeLay knows the courts erred: "'I'm very disappointed in our justice system. There doesn't seem to be justice,' DeLay told KTRK-TV." Why? Because he knows the law and they are wrong.
I am sometimes a little jealous of these individuals. As strong as my ego is and as fervently as I can make my case, I never believe absolutely that I am right.
