I think he was defending his industry that takes in all divers to explore their underwater world. He watches for those that need a lot of help, gives credit to those that don't, and really watches for those that think that because they know what a wing and backplate are, they don't need help ... cause those are the ones that really can cause harm. Again, if you pose, you're not authentic.
A backplate and wing do not make a good diver. And a jacket BC, split fins, and a snorkel do not make a poor one. Like any sport, understanding, talent, and practice make a good diver. Unfortunately, most divers refuse to practice, and most are pretty short on talent from what I've seen. However, I am unsure what "harm" is being caused by those who choose to dive in a BP/W config.
