Some vegans are extreme nut jobs
I followed an essentially vegan diet for a few years because of health problems I was having. However, it didn't help and I eventually returned to eating an omnivore diet. During the time I was a vegan I made many friends who wanted me to be their Facebook friend. However since outing myself as an omnivore all hell broke loose. I have now been branded as a traitor, murderer, disgusting person and liar---simply because I now choose to eat meat. I have been ridiculed and harassed. It's been a horrible experience. Those people are crazy!
