It's simple, really. It's not about flavour or fat content at all. If lamb wants to find its way into more American mouths, it just needs to get onto the promotional bandwagon, toot its own horn, and recast itself as "the Cute Meat" or "Lamb - we're not all baaaaad" or similar slogan. Hire Beyonce to one-up Lady Gaga and wear a lamb dress.
The greatest fear of disconnection with nature, and the widest response thus far, seems to be for children. At some point, society separates our young people from the natural world, reinforcing a doctrine that has been evolving for hundreds of years.
