TKD suffers (or benefits, depending upon your perspective) from heavy commercialization and all that goes with it. Arts and sciences are fundamentally at odds with commercialization. Art and science demand a degree of integrity while commercial interest demands profit. If integrity is standing in the way of profit, guess which one loses?I only said that, because that is one art that comes to mind, where you tend to see a lot of young kids with BBs. When you hear people reference the art as Take My Dough, well, right or wrong, you can probably see why people view that art the way they do. Is every TKD dojo out there using shady tactics? I honestly don't know. I'd really like to hope that there's a few at least, that uphold some quality standards.
