In the US it's different, though: Unlike in Asia, the conflict happens within a politically unified country. Also, one of the two "sides" in the US conflict is religious while the other one is more or less laical. In Asia, the conflict involves two countries (though the conflict may not be between the two countries themselves) and all parties involved are politically motivated.
I also get the impression that flag-burning, vase-throwing and all other kinds of vandalism seems to be the common norm on political rallies in non-japanese Asian countries. Confirm/Deny?
