I don’t see it exactly the same way, but there’s some good points. From a reader:

Though they are anathema politically, we all have our litmus tests for
sizing up pols. My only one: whether they would vote for an amendment
banning flag-burning. If they would, they can never receive my support in
dollars or votes because it would then be clear that they put politics above
right and reason.
First, not only is such an amendment unconstitutional (as the document
stands now), but it’s completely impossible to enforce and would serve as
nothing more than feel-good, pseudo-patriotic nonsense. The triumph of
emotion over logic.
Second, what would count as a flag? Does it have to be cloth, or would large
pictures drawn in crayon be covered? Do poster-sized glossy pictures of
flags count? Could I be jailed for burning a tie or shirt with a big flag on
it? What about those little flags on toothpicks that are in some desserts
and drink; I guess it’s 30 days for igniting a stack of those. What if the
particular flag I am burning only has 12 stripes and 49 stars….is it
official?
And why only flags? Shouldn’t we also protect other symbols of America? The
Statue of Liberty, the Constitution, the Declaration of Independence. I’ll
still be free to burn those, even though the sentiment is the same as
burning a flag.
And you have no problem with such a law. Do me a favor. Take a stab at
writing this law so that it isn’t completely ridiculous.
Good luck.
