Hmm. Let's see if I can help with this.

Actually, PETA is -- for all practical purposes -- the only "big name" behind the banning of foi gras in the U.S., and the only organication giving so much money into advertising their name and promoting part of their "work." Many other organications are more careful, both in their goals and their methodology. PETA is currently leading their website with their fois gras "successes" -- all of which count taking fois gras off the menu in individual localities and even individual restaurants rather than addressing any aspect of torture.

PETA is rather easy to bash. The only important thing to remember here is that they don't really care about animal husbandry at all, or any specifics of the treatment of any animal, or any scientific aspect of the raising of any food animal. Again -- ultimately -- their goal reaches much further. It's a good thing, too, since their specific ability to care for animals has been called into question.

"Eating fois gras ,,, ensures that an animal was tortured" ignores the body of evidence (supported by veterinarians and scientists) that geese and ducks do not have the "diver's reflex" (gag reflex), that force feeding is apparently pleasurable to the critters, and that -- within reasonable limits -- force feeding does not limit the mortality of geese and ducks about to be slaughtered for food.

Yes, there are issues. Is the feed auger appropriate, or is the pneumatic feeding more humane? How much is too much?

But when the question becomes something much more like "I don't eat fois gras, never have, and don't eat beef wellington either because I don't eat beef. Let's vote to ensure that nobody else can do any different." -- well, I offer that the question is the wrong question.

eth‧ics  /ˈɛθɪks/

4. (usually used with a singular verb) that branch of philosophy dealing with values relating to human conduct, with respect to the rightness and wrongness of certain actions and to the goodness and badness of the motives and ends of such actions.

I am, of course, only an opinion -- and may not be a popular one among a group of "ethical carnivores."
