Maybe we should ask if anything should be tolerated. Students kill each other over sneakers, so sneakers shouldn't be tolerated. People kill over lovers, so lovers shouldn't be tolerated. People have riots over sports sometimes, so sports should not be tolerated. We should all dress the same, dye our hair all the same color, eat the same food (and no meat) and all speak the same language. The world would be boring but no one would have anything to fight about. Or would they?
