Speciesism

 speciesism, in applied ethics and the philosophy of animal rights, the practice of treating members of one species as morally more important than members of other species usually due to exploitation; also, the belief that this practice is justified. The notion has been variously formulated in terms of the interests, rights, and personhood of humans and animals ( which are the same thing)and in terms of the supposed moral relevance of species membership. The term is exactly analogous to racism, sexism, and other forms of irrational discrimination and prejudice.

Humans tend to be speciesist by default and I can almost guarantee if you are not vegan you are a speciesist.
