You're making a lot of assumptions: I'm not a vegetarian, first of all. My point is simply that tricking someone into eating tofurkey is objectively more moral than tricking them into eating turkey, because both involve equal trickery, but it is incredibly improbable that anyone has moral objections to tofurkey (and in the specific case, this was a certainty). With a stranger it's more complicated because they might have a soy allergy or some compelling reason other than ethics to avoid the fake meat, but that's not relevant to the specific situation.
