For demonstrating why this dialogue was a non-starter. As you and many of your passionate supporters have made abundantly clear, veganism/vegetarianism is a quasi-religious commitment that, like religious belief itself, provides a community of belief bound by a common moral and ethical (and often aesthetic and political) framework. Of course, there's nothing wrong with this - many of us yearn to live on a higher ethical and spiritual plane. But don't try to impose it on others. For anyone over the age of say, nineteen, the belief that humans and animals are equal in dignity is no more demonstrable (or refutable) than the divinity of Jesus.
