I’m not good at the schmaltzy stuff, so I point you to this from Doc Zero:
[…]the American flag has never been desecrated.
She is the symbol of a unique nation: born in the defiance of tyranny, baptized in the destruction of slavery, and coming of age when it rescued the world from genocidal evil. Those who destroy our flag earn nothing but our contempt. They abuse their freedom of speech to level such an insult… but if you embrace the freedom to perform only virtuous deeds, you will soon find that what you’re holding isn’t “freedom†at all, as the arbiters of “virtue†lay their heavy hands upon your shoulder.
Anyone who seeks to desecrate the Stars and Stripes, on either foreign or domestic soil, is a fool. The power of that flag is far beyond their reach.
As they say, read the whole thing.
