It is American tradition (and yes, Americans have some admittedly pretentious flag-related traditions) to dispose of flags that are worn-out or muddied beyond cleansing or otherwise damaged beyond the point that they can be displayed with dignity by burning them.
This burning is generally done, I believe, by placing the flag in a container and burning flag and container together.
Many American protesters, upon feeling that the honor of our nation has been dragged through the mud and shredded and damaged beyond dignity, have expressed this sentiment by burning the flag.
This burning is of course done in public, because the intention is to make a political statement, not to dispose of a piece of worn-out cloth. Note, however, that the underlying motivation here could be characterized as patriotic. It could also be characterized as anti-patriotic, depending on your view of patriotism. Does one say “My country, right or wrong” and remain loyal and uncritical of one’s leaders even when they are embarrassing the fuck out of the nation and ruining its reputation? Or does one take responsibility for the wrongness of one’s country by saying “My country, right or wrong, and current wrong as all get-out, and I think it sucks”?
(There are also people who burn the flag as a way of saying they reject the country and everything that they believe it stands for. Theirs is also a political statement and should also remain legal.)
The funny thing is that if everyone agreed that there was no big deal about burning the American flag, it would lose its value as a shocking political statement and few people would bother doing it.
Anyway, as is the case with most American posters to this thread, I see nothing wrong with Bush signing the flags, and it certainly isn’t illegal; but I note with wry amusement and a sprinkling of minor-league indignation that he is among those who have pushed for a stupid amendment that would make both flag-burning and flag-signing an illegal and punishable act.
God help us if this is the only stupid or inconsistent thing he’s done that sticks in people’s minds though.
