I have felt resistance to the term "lacto-ovo vegetarian" ever since first seeing it in print many year ago. It seemed then, and it still seems to me, that connecting animal-based food choices to the term "vegetarian" was an attempt to make respectable the consumption of milk and egg derived foods. Somehow it was better and less problematic in terms of one's health, the health of animals, and the health of the earth.
So, I'm grateful to Dr. Joy for coining the word "carnism" because it makes it possible to correctly label the choice to eat and drink from the bodies of cows and chickens. I think it is time we reclaim the word "vegetarian" and relegate "lacto-ovo" to its true domain. In truth people who choose to eat foods derived from cows and chickens are "lacto-ovo carnists."
