Yeah, I'm A+, so I don't believe in eating by blood type, although it's nice in theory.
The only thing that could make me a believer would be for it become physically possible for me to do it and feel well. If that happens some day, of course I will believe.
Besides, it's a nice idea to not have to eat cute little animals... And it would sure help me to fit in better with all of my hippy friends. And wow, I could go to Buddhist meditation retreats and live on hippy farms in Asheville! I think feeling ostrasized because I don't feel well eating vegetarian is part of why it makes me so angry when people say it's the only way. It feels like everyone's loving the animals and the idea of being vegetarian more than they are interested in loving a sick girl.
