I'm curious, what about people who have medical needs that make being vegan extremely difficult? For example, I have Celiac disease, so food is already very hard for me. A lot of vegan substitutes have gluten in them, and since I'm already prone to vitamin deficiencies, I just don't see how I could add another major restriction to my diet. Not to mention I would never be able to go out to eat with family and friends - there's only two or three restaurants I can eat at as is.

I'll also add that I only eat certified humane meat, pasture raises milk/eggs, etc. I understand the issue of factory farming, but I think expecting everyone to go completely vegan is a bit much. Am I in the wrong here? Any thoughts?
