If you feel the flag is "damaged" it should be burned. It does not provide an excuse to write on it.
Ok, it was a pretty poor analogy.
It was a really p*ss poor analogy. While I agree with you that we should not be writing on flags, this flag is special.
This flag is not just a symbol. In a way, this flag is all of us.
If the US Marines don't mind, and will proudly fly this symbol of us while killing the murderous b*stards, I don't mind either.
People shouldn't write on their flag. However, people have written on their flags before and will again. Especially battlefield flags.
I would much rather have it discussed in a forum like this than to have the first amendment "new and improved" to decide what is and is not defined as desecration v. tackiness.
