I guess the point I was trying to get at is that everything is arbitrary, and we draw our lines where they best suit our lifestyles, ethics, personal morality, or goals. After all, mushrooms are more closely related to plants than to animals, plants have been shown to warn each other of danger and even behave altruistically, etc. So I figure, let people label themselves how they want to be labeled. My younger sister is a vegan (doesn't consume or use any animal product), my older sis will eat fish (also an arbitrary decision, since, biologically, there's not really a "fish" category), I'm an omnivore but I couldn't bring myself to eat a cat or dog or monkey. We can all enjoy a good fungus, though.
