SHW, I think that you have failed to prove a few vital points.
1) A
purely vegetarian diet is more beneficial than one with
limited meat intake. I don't think you'll find a dietician anywhere (now that Atkins is dead

) who will tell you to eat meat with every meal, but neither do I think a purely vegetarian diet is wholly a goood thing.
2) We have a moral obligation to other animals.
3)
Most vegetarians have a nutritionally well-balanced diet.
