you don't burn the flag
I don't burn the flag unless it is to dispose of one ceremonially. And nobody had better burn my flag, either. But you know better than to enact laws that restrain others' right to free expression. I won't support you if you do, and I'll definitely work to prevent this legislation from passing. This is one plank in the Republican party's convention platform that is statist and wrong.
You have a right to use it as firewood, if you wish. I would be enraged watching someone burn the flag, because I love my country. However, I love my country because we are free to express ourselves and live our lives as we wish.
