Speciesism (/ˈspʃˌzɪzəm)

speciesism

Speciesism involves the assignment of different values, rights, or special consideration to individuals solely on the basis of their species membership. The term is mostly used by animal rights advocates, who argue that speciesism is a prejudice similar to racism or sexism, in that the treatment of individuals is predicated on group membership and morally irrelevant physical differences. The argument is that species membership has no moral significance.

The haunting movie  Earthlings  visualizes speciesism pretty good.
