I'm sure if you took a poll of the general population that would be correct. However, I think most conservative commentators, judges, and others with a career in law or politics are against the amendment. For example, I would hardly call Scalia a libertarian.
Correction: a career in law or politics and not directly accountable to the voters.
I agree with Scalia 99% of the time. However, given the choice of calling myself a Reagan Conservative or a Scalia Conservative, I'll pick Reagan. Since our beloved leader has left us, I've taken to looking to Newt Gingrich for my cues. Want to guess which way he leans? The point is, we need to accept the fact that soldiers have died for the American Flag. It is more than the sum of its fabrics. Many of our soldiers have laid down their lives for it. As such, it deserves special protection. In your learned opinion, I'm guessing that a guy blowing up a pile of copper would deserve exactly the same penalty as some raghead blowing up the Statue of Liberty. "Free Speech," right? Not in mine.
