Boundaries as In I don't want them coming up there with a gun and shooting the crowd...yeah there should probably be some limits to what they can do and say. Comedians like all humans, should have a filter and know when something is pushing it too far. If a joke is funny to 8 people and offends 8 billion, it's probably too far. It is amusing, when one group will say yeah that black face joke is hilarious whats the big deal, and than throw a fit over the christian joke or someone poking fun at their political hero.
