CMV: Flag burning should not be illegal in the United States

This is an odd position for me as I've changed over the years.

Early on, I was for the idea of making flag burning (in the United States) illegal. My opinion was based on the fact that it shouldn't be allowed because if you don't like America, then don't live here and don't visit. (I realize that there are other reasons people burn the flag, but I think this is one of the typical attitudes of people doing it: to show a dislike of the country and/or its current government.)

I still have that mentality, for the most part, but I have since more so disagreed with making flag burning illegal.

Ultimately, I see it as something that is covered under the 1st Amendment, and while I heavily disagree with someone burning the American flag, I would never do it myself, and I think they're an idiot for being so unpatriotic and sometimes ironic, at the end of the day, I believe it is their freedom and right granted to them by our nation's Constitution to express themselves in this manner. Just as it's perfectly legal to speak out against the President, Supreme Court Justices, or any other member of the government or the government itself, so is flag burning, in my opinion.

The 1st Amendment is just one of many reasons I'm proud to live in this country and expressing our dislike or disfavor is one way of expressing that right and sometimes that expression is done in more ways than just with words.

The only way I'd say it should be illegal is when it becomes more than flag burning, such as if they then use the burning flag to set a house or another person on fire. But at that point, it's no longer flag burning that would lead to them being arrested and charged with a crime but something like arson or attempted murder. The other way would be if someone was doing it on private property and the owner of the private property didn't want it, then they should not be allowed to do it there either.

So I'd like to get some feedback from others why I should change my mind.

Many flags are made from polyester or other man made material.  Burning these produces toxins such as dioxins and other carcinogenic chemicals. 
Sure you have a right to protest, but not at the expense of other people's health.
