SG,

Totally agree that you break ties towards freedom.

An interesting line of thinking might also be -- is the Koran burner choosing this mode of expression because it communicates some meaningful opinion in a unique way? Or is he choosing this mode of expression to be intentionally inciting the other side? This is similar to burning the US Flag (an action I would have argued deserves protection) rather than using your own words to express your thoughts.

In BOTH of these cases, if you can find IMMINENT and LIKELY violence (even from wingnuts) then you could make the I-think dangerous argument that any intent to incite means the burning of either is NOT protected. That's unfortunate, as again the wingnuts are setting the line.
