I'm all for my views being challenged. Vegetarianism is perfectly fine for me. It's a sensible, more environmentally conscious and healthy lifestyle (whether intermittent or not). Veganism, on the other hand, is an ideology I don't support. It's rigid and inherently elitist. Whether intended or not, it stokes fundamentalism and fanaticism (as in the examples I've mentioned in another post), and also does not provide all the essential nutrients humans need (according to WHO, Warwick Medical school, Gibbs, Capuccio etc). My view of veganism is based on learning everything I can about what veganism is and deciding that this is something I do not support.
