To draw an incredibly stretched comparison to vegetarianism instantly tells me everything I need to know about the way you think. It's overwhelmingly sanctimonious.

On one hand, it's an idea of organic growth and bringing fruit. OTOH it presumes that the meat is left out!

Can you expand on that a bit?

I understand why you would think that, and I did too at first, but I'd encourage you to give the post another read. What the author's trying to do is precisely the opposite. He wants a good social script to ensure he's not sanctimonious or argumentative: he's sure your brisket is great, he's got no problem with you and your friends enjoying it, but he's not personally interested in it because he doesn't eat meat.
