Speciesism is the notional act of assigning different values or rights to beings on the basis of their biological species, by analogy with such terms as sexism and racism. The term is used and considered meaningful chiefly by advocates of extensive animal rights -- that is, those who believe that speciesism, so defined, is ethically incorrect and its consequences morally wrong.
Like other words of political and moral disputation (such as the Marxist use of "exploitation", or the various meanings of "sexual liberation"), use of the term implies a certain position on the subject it discusses. To refer to speciesism implies that it is possible and desirable to treat members of various species -- specifically, nonhuman animals traditionally considered "lower" animals -- with moral value equal to that which society bestows upon humans.
The continuing debate over companion animals is a frightening example of our movement's propensity to engage in selective morality, applying different standards to various species. Billions of farm animals suffer terribly each year, but no one would suggest that our movement take over meat-packing plants to operate them more humanely. Instead, we use our energy to vigorously protest a meat-based agriculture system that injures nonhumans and humans alike. With companion animals, however, society uses and abuses them for profit and pleasure, and our movement obligingly operates the slaughter houses to dispose of the "throwaways."
Instead of recognizing our movement's historical and contemporary role in this holocaust, many leaders continue to rationalize it on the basis of a "humane" death being preferable to a "miserable" life - further arguing that we are best able to provide this "merciful" end. Desperate humans are grievously suffering by the tens of millions all over the world, but who can imagine relief agencies endorsing systematic euthanasia as an acceptable policy........
