Are Oysters Vegan? (REBROADCAST)

I’ve heard every justification for the consumption of animals, but I was a bit stunned when I heard someone claim that vegans should eat oysters because bivalves are “basically plants.” No doubt there are grey areas in this whole attempt to live as compassionately as possible. But even the fuzzy lines are still lines. If I let you eat oysters, would you stop eating cows?
