Flag burning should be legal, if it’s your own property and done safely etc. The protection of what the flag represents (liberty, including freedom to express yourself without state interference) is far more important than protecting an individual example of the flag itself.

In a way, I’ve always felt people who burn a US flag -safe in the knowledge they will suffer zero consequences, because of the freedoms that very flag stands for- are complimenting rather than insulting it, even though they don’t mean it that way. Burning one US flag doesn’t burn every US flag; it makes every other US flag shine a little brighter and fly a little prouder.
