Isn't it the case that if you eat cheese or drink milk you pretty much (as an omnivore) have an ethical obligation to eat veal? Because of the dairy industry, British boy calves were just disposed of at birth (no good for dairy farming), because Brits had become very resolved against veal. Now with a slight resurgence of veal consumption, they're more likely to live a bit first.
Of course, it's not much if a life... But better than newborn cow scrappage, which is what has to happen otherwise, if we are to have milk and cheese.
Have to say, as an observing omnivore, I find veganism - or at least non-dairy consumption vegetarianism - a more ethically consistent position. But then I guess vegetarianism isn't simply an ethical choice, and cheese is less squick-making than flesh, so it could be that. But in terms of killing animals to make food, dairy has a pretty high body count.
