I haven't heard her or anyone else say the Koran burners don't have a right to do it.
They're basically just saying it's a dumb thing to do. And it's their right to say so.
On the other hand, calling out, or labeling, those who do not believe that burning the Koran (or Quran or whatever) are “dumb”, when a good portion of those who support you disagree with that sentiment, may not be the “best” choice of responses for an aspiring political “phenom”? I suppose what I am attempting to get across is that although I personally support and favor Mrs. Palin on just about any given topic, on this particular issue I simply believe that the better answer for her would been not to supply one in the first place, but again, that is my own personal opinion.
