I don't think that the classification being done is "good" or "bad". Rather we classify things as "okay to eat" and "not okay to eat". Vegetarians are not classifying animals as "good" and plants as "bad". Fruititarians are not classifying plants and animals as "good" but things that fall off plants as "bad". Everyone is doing the same classification: "am I okay with eating this, or am I not"; the only trick is that different people come up with different answers to that question.

To be clear, my classification is tuned very far to one extreme. That is to say, I would eat anything given the opportunity (in some cases necessity comes into play).
