keep in mind that I am not actually recomend eating people.. unless it's in an intimate sexual manner and not really damaging.. then I'm all for it.
but.. if it came down to a dog/cat or a person that I didn't have any emotion invested in and there was no other choice.. well... four legs good, two legs dinner. (and there would be more to eat! and as to the obese thing.. well you could render all that fat down to make soap or butter... who knows! the options are endless
