This is why I vigorously oppose a "flag desecration" amendment to the US Constitution. One man's desecration is another man's message. The flag is a symbol, a very powerful symbol, but only a symbol. The Constitution of the US is a mechanism for limiting the power of government and is not the proper means for honoring the flag.
Posted twice by accident not for emphasis.
A related point is that by putting BS on the flag it clearly signifies that there is no such real flag. It's tags it as a BS creation of CBS.
