In school, I picked on guys with fat jawlines and big chins. I would box up my neighbor with ease, also big jaw. This is what "zero-tolerance" is doing.. It's making you kids not realize that physical dominance is more than a pansy with a beard or a fat jaw. Those things mean virtually nothing. You can learn this late in life by doing some submission grappling. I WILL say that most, but not all, of the good wrestlers I knew had more masculine jawlines. But back in the 90s we would punch them in the face as well.
