Well said.
My friend from the very peaceful Faroe Islands posted this on his Facebook page earlier today: "Lack of empathy is the root of all violence. To understand violent actions, we may need to have empathy with those that ("appear to") lack empathy."
It's a hard task to accomplish sometimes -- especially in the face of such destruction. But the true roots of the riots (beyond the initial event itself), need to be explored by those in charge. If not, those 'cunts' your friend described will literally ruin everything -- including the ideological points -- for both sides.
...Another great one, from a London bookstore employee: "We'll stay open, if they steal some books they might learn something."
