But I do remember with amusement an acquaintance of Iced Tea's who was a dedicated vegan, with a 'Meat is Murder' sticker on his portfolio and everything, who used to go to Wendy's every day and order a plain baked potato with no butter or cheese or sour cream. Apparently, it had not occurred to him to bring his own lunch, or just to not eat at a restaurant that would take his dollar and use it to pulverize cattle by the millions.
Come to think of it, I do have a gripe with people who apply their quirky dietary notions to animals. Vegetarianism is fine for people; it might even be heroic. Choosing not to eat meat is a valid choice for adaptable humans, whose versatile metabolisms and mastery of technology allow them to forsake dead flesh with relative ease (though see above); however, dogs and cats just aren't built that way, and it saddens me to see a pet get impaled on the spike of self-congratulatory human behavior in any manifestation. I recall an old boss of mine who kept her dog on vegetarian meal, with the result that the animal was sickly and tired like a strung-out junkie; or reading a pamphlet in my vet's office about cats who require rather serious medical treatment every year because their owners have imposed their own dietary choices on them.
Think things through, people. Honestly.
