Diet debate down to ethics, not legality

It seems “Dr” Frank is unable to discuss an issue intelligently, and can only respond with rudeness. I agree that eating animals is legal, but that doesn’t necessarily make it ethical. The African slave trade was legal, but how many people today would say it was ethical?
