I think you`re right that Americans have the right and obligation to question all things governance. We should question the legitimacy of the politicians and administration.
But to question, debate, argue, and dissent ought to mean a rational, reasoned, and thoughtful process.
Today, the polarization between liberals and conservatives is nearly total. As a conservative, it seems to me that liberals prefer to shout, not argue. Not always, but generally. It also seems to me that liberals would prefer if conservatives didn`t argue at all and were removed from the equation.
That being the case, reasonable conservatives and liberals can, and do often have reasoned discussion. Unfortunately, we`re at a point where not many reasonable people are left.
To address only one of your points, where you propose there were no terrorists in Iraq until the US got there. I wonder where you get your information? How do you gauge the accuracy of that information?
Conversely, how can we determine the accuracy of the information telling us that there were terrorists in Iraq, or WMDs?
What all of us are facing, liberals and conservatives, is the breakdown in credibility across the board. We have almost no legitimate news reporting anymore, and not a whole lot of objective facts to examine about anything.
Because we have to delve into separate reports and investigations on our own, the "facts" and resulting conclusions we draw, all are subject to rejection. "I don`t believe that."
And so we`re pretty well on an irrevocable course. The overall society is left with only direct, empirical evidence to deal with. We`re wiping out the whole concept of analysis, prediction, assessments and reasoned supposition.
That means we`re left with, "I`ll believe it when I see it." Empiricism.
