but i think your one is different, i mean you won't go infront of a whole bunch of black people and say on their face "Hey you black bas*****!" - i don't think you will, but the cartoonist did something similar, and some people didn't like it and wants to retort by killing him, so let them kill each other, and both end up in jail, as long as no other people are harmed, i am happy.
but seriously i don't mind them killing each other, they both deserve it.
