You could lump in all diets for religious reasons here. Basically, it's odd to think the almighty has enough time to monitor your snacks, but whatever floats your boat. We choose Kosher not because it annoys us, but because it's annoying to practice. You not only have to avoid certain animals and have others killed in the right way, you also need foods blessed in production and have an extra set of dishes. On the up side, bats are not kosher to eat, which probably won't cramp anyone's style.
