Actually, I'm also with Walt on this.
I eat meatless meals not for religious beliefs, not for economics any longer (although with the cost of meat, those days of gift-wrapped meat from the 70s seem like yesterday!), not for some higher moral purpose...I eat meatless meals because I LIKE them. And frankly, it's no one else's business.

And yes, IMO, if you launch into some higher reason for any menu plan other than that the way you eat is your preference, and none of their business--well, yeah, you ARE preaching your beliefs. In my experience, that is just pointless and I don't have the time or energy for that. I've got more important things to do, like untangle my stereo speaker wires. Seriously...this is a menu choice, not a 'cause.'
