I would not burn a flag, I would not support or take anyone who did seriously, I would not join a group of people watching a flag be burned, I would not watch a telecast of it and I would not support the media outlets who displayed it. I would voice my opinion against it, I would not give someone who performed the act a moment of my time.
I do not agree with it, I understand it to be a form of protest but it is ideological and symbolical and nothing more. No one is being hurt and no person who ignores it will ever know it happened. I would not campaign for a penalty for people who did it, I wouldn't want to inspire others to push the limits of the state authority and I would not want the state to feel it needs to intervene on a social issue like this. The person who would commit this act does so in protest to what the flag means to them. Perhaps they feel slighted, perhaps someone under the flag hurt, killed or desecrated something sacred to them. Personally I think its a meaningless gesture, our flag is a piece of cloth with a pattern either printed on or sewn in. My loyalty lies not with symbols it is with the idea that a nation of people can govern themselves, that freedom and liberty are dangerous things but they make life taste sweeter, and against the harm they often bring and the responsibility they always require, they are worth more than my own or anyone else's feelings getting hurt from time to time.
