Bobonich, who has been vegan for over 11 years now, believes that it is difficult to draw a line between animals that we can and cannot eat.

“If the line is having beliefs, I believe that some animals have beliefs,” he said. “We don’t eat people who are in a vegetative state. If the distinction is that animals cannot do things such as linear algebra, a lot of human beings should also be eaten!”
