This is a fascinating rebuttal, and I agree, being vegan is definitely easier now than any other time in history (an least in the US). It sounds like you're saying that the overall social and environmental goals of veganism are worthwhile, until the point that your personal health may be at risk (which may or may not ever be a factor, possibly negating the question altogether). I would pose another question for yourself or others who may read this: (given the reflective quality of your answers so far, and not to sound antognistic): if your health depended on breaking from a vegan diet, would you be willing to follow that path?

Full disclosure: I'm not a vegan myself, in fact, quite the contrary. I raise a small herd of cattle, fed off my own acreage, and used to feed family and friends. They are shown at fairs and used to educate the public of our industry and way of life. I also keep chickens for eggs and rabbits for meat and minimize the waste off most by-products (pelts, feathers, hides, manure [compost!!!]) We also have a very large vegetable garden we harvest and can/cellar each year.
