Supplanting, but related to, the sort-of-mosque that's sort-of-not-built-yet at a place that's sort-of-near-Ground Zero, is the story about a flamboyant Florida pastor who plans to hold a bonfire of Korans on September 11.
I'm not a fan of book burnings of any sort. Burning it is an act of symbolic hatred and aggression towards Muslims and is in extraordinarily bad taste. It will likely have a net counterproductive result. And the most effective way I can imagine to discredit Islam is to encourage people to read the Koran. They won't like a great deal of what they find in there; a lot of it is morally indefensible.
And the commander of American forces in Afghanistan has very publicly pointed out that by having a Koran-burning ceremony, this pastor will be inflaming the masses of people whose hearts and minds America is busily trying to win, at a cost of much blood and treasure.
But it is perfectly legal, perfectly Constitutional. Maybe not perfectly legal; as I understand it, a local air quality management board has denied a permit because of concern about toxic fumes that the bonfire would release, which I find quite amusing.
If Muslims, and in particular Muslim Americans, find this act offensive, they are free to protest it in whatever form they wish, ideally to persuade the pastor not to do it at all. Pointing out that a Bible-burning would be offensive to Christians strikes me as an excellent starting point for an argument as to why the pastor ought not to have a bonfire of the Koran.
In America, no one has a right to be protected from someone else making an offensive statement. There is no violence planned for the bonfire of the Koran and assuming that the air permit issue has been cleared up (so to speak) there is no legal impediment to the demonstration, nor should there be. This particular bit of public expression strikes me as reckless, in poor taste, and profoundly ill-considered. But we don't need the Constitution to protect speech that is popular or even generally acceptable. We need it to protect speech that is controversial.
This more than qualifies.
