How strict are these vegetarians?
Is it possible that they would rather die than live off meat cubes, or is Riker just an old foogie not completely in touch with the nextnext(next?) generation?
Maybe if they weren't such militant vegetarians what happened on Equinox wouldn't have been such a big deal? Hell would it be more forgiveable if they were eating those space beasties rather boiling them up for fuel, and more importantly... What would be the best wine to serve with broiled space beastie?
