Unfortunately, the vast majority of people don't seem to be bothered enough by the idea of animal suffering to want to change the way they eat. If you look at the health arguments for veganism, on the other hand, they are extremely compelling in the context of a country where 30-50% of the population seem to take pride in their lack of empathy and admire those who care about no one but themselves. People in the U.S. take all kinds of medications with horrible side-effects in order to slightly reduce their cholesterol levels and their likelihood of dying from a heart attack. Simply going vegan can have a much larger impact, not only on cholesterol and heart disease but also on the risk of cancer, Alzheimer's disease, kidney disease, diabetes, diverticulitis, etc. The factory-farm industry has been lobbying hard to confuse the issue, but the facts cannot be kept from the public forever. I have come to believe that the industrialized world will turn majority-vegan within the next 20 years or so as a result of the health argument. As a consequence, animal suffering will be greatly reduced. If the health argument for veganism can make large numbers of people stop eating animals, discouraging the health argument for veganism and calling health-focused vegans "not really vegan" is effectively a way to support the torture and killing of animals, no matter how vegan one thinks one is.
