How is the philosophical boundary for vegans typically distinguished from that of a vegetarian regarding animal ethics?

Answer

For the vegetarian, the boundary is the killing of the animal for food; for the vegan, the boundary is the use of the animal for any product.

Vegetarians often stop at avoiding eating flesh, sometimes accepting dairy or eggs from humane sources, whereas vegans maintain that any commodification or use of an animal is unethical.
