I understand how strongly so many of my fellow veterans and citizens feel about the flag and I understand the powerful sentiment in state legislatures for such an amendment. I feel the same sense of outrage. But I step back from amending the Constitution to relieve that outrage. The First Amendment exists to insure that freedom of speech and expression applies not just to that with which we agree or disagree, but also that which we find outrageous. I would not amend that great shield of democracy to hammer a few miscreants. The flag will be flying proudly long after they have slunk away.
