"(G)astronome Jean Anthelme Brillat-Savarin tells us that 'stock to a cook is like voice to a singer.' Can you really justify taking away my voice? When I have vegetarians over for dinner, I'm already making a sacrifice by forgoing a real entree in favor of a meatless one. Fairness and common sense would argue that, in return, vegetarians shouldn't make a big deal about some small amount of a near-invisible (if crucial!) liquid. I've compromised my culinary integrity enough already — now it's your turn: Vegetarians and vegans, chicken stock does not count as meat."
