Ok, i'm not really in the mood to discuss whether or not it is right or wrong. But I would like you to explain to me how you think it is practical. Because humans just so happen to be omnivores. And there is no way you are going to get any significant portion of the population to agree with you. Vegans are an extreme minority, every vegan I know has eventually gone back to eating meat, some after being a vegan for 8+ years. I'm just curious how you expect this to be the case. The only way this could happen is if you were to enforce it.
