As an American, I feel the same way about it as I would someone burning the American flag. As long as it is done safely and in a legal manner (ie not in the middle of a crowd or on public property without a permit) it is his flag to do with as he wishes. I don't support people who do it, but I support their right (freedom from government punishment) to do so.
Title is extremely misleading.
It should be "UFC Fighter Sets fire to a picture of his opponent holding a flag"
What a nob-muncher.
That's three and half minutes I'll never get back and he didn't even burn a real flag.
I do not approve the burning of flags, but I cannot say I care very much either.
Not enough to click on that video, even.
