You only read what you wanted to read. Disagreeing with policy and principal but being respectful at the same time is not unthinking respect for authority.
As I said on another thread here today: Respect is something earned. Neither one's age nor position means that they should automatically get respect. I'm not sure Bush has done anything to earn respect.
That being said, I'm not one to call Bush, or anyone else for that matter, names. However, I do think that he is dumb. And, there is really no other way to say it. Obviously he is well educated, but he is unable to apply that education. If saying the truth as I see it is disrespectful, then so be it.
