What I don't like is pseudo-omnivores that only eat the boneless skinless chicken breast, say - the meat that magically appears on the safeway foam tray.
If you're gonna eat meat you may as well eat as much of the animal as you can and use the rest. Tongue, oxtail, heart, all good stuff. Too much cowhide - I'm not a leather worker. No use for chicken feathers. Too small a customer for the rendering plant to deal with. We burn them.
