As offensive as it would be to Muslims, obviously, there are no laws (at least in the U.S.) against it, and it would constitute free speech per our Constitution.
If this is about the recent Quran burnings in Afghanistan, that was accidental. On the other hand, if this is about pulling a Terry Jones, I would not partake in such an action, even though I strongly condemn the actions of Islamic extremists. But be that as it may, it's still free speech.
Of course, I think wishing death on them is morally wrong. All I want is for them to stop blowing themselves up in crowded areas, and to treat women better.
