Quite the opposite. We should ALWAYS question the applicability of the Constitution. It is the only way to test our laws. We do this daily was we consult case law, codes and the Constitution. Do our laws fit within the framework? Do they violate our basic rights? I don't see questioning the Constitution -- or even discussing change to it -- as a step down the path of "shredding" it. Rather, I see it as our duty to continue to question all laws against that framework. And if change *is* needed, we operate within the process laid out in the Constitution to change it.
I'd love to see Executive Orders and judicial legislating be a thing of the past. Courts don't belong making policy like they do now, and the Executive does not belong making laws like they do now.
