This does not in any way suggest that we, as humans, shouldn't seriously reconsider our treatment of animals in general and certain other species in particular. But chimpanzees can never be "people" because they aren't.
Words have meaning and changing the definition to fit our personal "beliefs" or "worldview" or "fantasy-of-how-life/the universe/and everything should be" does not change reality.
It just doesn't.
We can all hug and sing "Kumbaya" but the world is still a messy place where there are snakes in the grass and lions eat antelopes.
