"Animals are not people. They should really cue vegans in on this fact."
Well, the thing is, vegans don't really care about something's species. If it can feel emotion, then vegans want to protect and care for it. Vegans (in general), are like Fluttershy. They care for all creatures, no matter what kind.
Come to think of it, I bet Fluttershy would really hate most humans for what they think of non-humans.
