sometimes the little lobsters have to band together to take on the big lobster to avoid getting their claws chopped off. sometimes they have to petition a bigger lobster than their lobster boss to intervene.
and while their lives may often be far from perfect the little lobsters have the right to criticize their world and whatever predatory practices the world allows, rather than naturalize them with lobster comparisons.
