Well at least they provided a nice list with usage examples and how to pronounce the damn words. That's miles ahead of most of the others.
On the vegans, thee are a surprising amount tat argue that non human animals shouldn't eat meat either. Before you think this is a joke, I've read at least one lengthy argument from a vegan saying that humans should use their intelligence and science to make all animals on the planet vegans. They, along with creationists(in trying to prove the "green herb, coconut t-rex" thing), often cite a book about a vegan lion cub called Little Tyke. Yes, like that joke from Futurama. As far as I can tell it was based on a flawed and biased study, and is only used as an argument from the two groups listed, the book being published by a creationist publishing company. As one person arguing against the book when it was brought up once said, "Well yeah you can make a lion hate meat, all you have to do is beat it whenever it goes near a steak".
The book I thing played no small part in the recent movement by some vegans to make their pets dogs and cats vegans as well. This honestly infuriates me, especially with cats. Dogs are somewhat omnivorous, but felines are obligate carnivores, meaning they need meat. There is a reason cats and other animals will eat all parts of their prey. They need all the nutrients, not just the meat. Felines specifically need taurine, and organic acid. Humans most often encounter it in modern times in energy drinks. Cats need taurine and their diet, and if they don't have it they will go blind. Cats either get taurine from the meat of prey or from manufactured cat food containing meat. The problem is that these "vegan" cat foods don't have taurine in them and are thus harmful to the cats. These people in particular piss me off so much it's a good thing I've only ever encountered them on the internet.
