If you gave up eating meat, then eating "pretend meat" is just a silly way to want things both ways.
I've also never been able to understand that. I find that hypocritical because it's like saying, "I don't want to kill that poor animal, but I sure love the way it taste." Though, I myself have never had "veggie meat," so I can't say how much like the real thing it tastes. (Anyone have a personal review?)
That analogy is referring to those who are vegetarian for moral reasons, but I'd imagine those who have that diet because they don't like meat wouldn't seek an imitation. (?)
