Hi my brother you became a vegetarian, I wonder what motivates him.
Perhaps vegetarianism is his form of animal rights advocacy.
So it must be some kind of a new ideological movement ?
Animal rights do seem to be a relatively new phenomenon. The term speciesism was only created in 1970.
Was it started by hippies ?
Hippie
A hippie (sometimes spelled hippy) is a member of the counterculture of the 1960s, originally a youth movement that began in the United States during the mid-1960s and spread to other countries around the world. The word "hippie" came from "hipster" and was used to describe beatniks who moved into New York City's Greenwich Village and San Francisco's Haight-Ashbury district. The term "hippie" first found popularity in San Francisco with Herb Caen, who was a journalist for the "San Francisco Chronicle
the basis of their species membership. In 2001 psychologist and animal rights advocate Melanie Joy coined the term "carnism" for a form of speciesism that she argues underpins using animals for food, and particularly killing them for meat. Joy compares carnism to patriarchy, arguing that both are dominant normative ideologies that go unrecognized because of their ubiquity:
Sandra Mahlke argues that carnism is the "central crux of speciesism" because the eating of meat motivates ideological justification for other forms of animal exploitation.
