" Old habits die hard, but that does not mean they are morally justified. It is precisely in situations where both moral issues and strong personal preference is coming to play that we should be most careful to think clearly. As the case of meat-eating shows, however, sometimes our brute preferences determine a moral thinking rather than the other way around. Many people have said to me "Yes I know it's morally wrong to eat meat, but I just love hamburgers. "
