Why might some people not agree with animal abuse?

Most animal rights activists place their generalized focus and awareness on the issue of animal rights. Animal rights activists do empathize with the negativity that comes along in the human rights movement, along with situations that humankind faces.

Animal rights activists, however, feel that the consideration of a right to life needs to be extended to animals, and the animal rights activist will most always stand up for the animal before the human because the animal itself, has no voice on it's own behalf in the human world, as compared to the human having it's own voice and authority.
