I'm not saying that the OP is just completely wrong. But I make the counter argument that many of us already DID know how to play. . . then this. It also goes deeper than that, honestly, and I wholeheartedly invite you to take a look here at some of the points made.

I make no demands for rotations or proof, and I agree some people really DO need to learn how to play their job better. But "learn to play" is simply too flat a statement to make.
