One thing many vegans don't get about non-vegans is that we're frustrated at veganism for the same "reasonable if not valid" reasons. I've had some vegan family/friends have serious health issues directly related to their refusal to eat meat. Yes, there's a lot to that, and it usually spawns from people easily prone to PTSD being made to watch some disgusting documentary about the meat packing industry and going full starvation on and off until all their hair fell out. Is it veganism's fault? Not directly.

It's kinda like the Catholic Church. There's SO FEW pedophiles in the Catholic Church, but for anyone who has been touched by that, the Church itself is tainted far worse than the facts allow.
