But the original challenge was: So as a result humans and animals are equal. Prove me wrong, if you can!
Not: Do humans and animals have equal rights?
The answer to that is obviously no. Rights, in the sense we're talking about, are artificially constructed by humans to govern other humans (and exclude non-humans). The idea that humans do, or should, have equal rights is a noble pursuit. The idea that animals deserve any rights at all is -- to my understanding -- a driving principle for many vegans.
The answer is no. But it should be YES. Humans and animals should be equal in dignity and rights.
