It would indeed be troubling to see an
amendment to prevent flag burning. I agree that this could be a step to limiting other forms of legitimate
expression.
It is ironic that mistreatement of the American flag for purely commercial purposes is ignored or even accepted. What I have in mind here are the huge American flags which typically fly over car dealerships (at least in the south). These flags fly in the rain, at night unilluminated and in shreds, all to show the "patriotism" of some business.
I find it much more offensive to see the callous disregard of our national symbol for economic or political purposes than to see it burned for honest protest.
