I think almost everybody on this board knows that I've gotten GUE training, and that I love what I've been taught, and try as hard as I can to follow the principles, and that I aspire to doing more training with GUE.
But I'll admit that I suspect the GUE/DIR approach selects, to a certain extent, for jerks.
I base this on my experience in general surgery. When you take something that's hard, and you have a training process that is difficult and stressful and that not very many people do, and at the end you have skills few people have and can go places and do things that most people can't, you'll find that process can attract a certain kind of person. The unfortunately sexist word "macho" comes to mind.
Most general surgeons are great people. They have deserved pride in what they've learned to do, but a lot of humility that comes from having failed and knowing there are finite limits to their competence. But some are thoroughgoing jerks -- arrogant, elitist, autocratic and contemptuous of others. Some sneer at non-surgical specialists (referring to internists as "fleas" for example, because all they can do is crawl around on the outside of the patient and suck blood
).
I suspect that technical diving in general can select for the same personality type, and in fact, that people of that type, if they dive, are more likely to gravitate to specialized training. So your chances of running into an arrogant loudmouth technical diver are probably higher than running into an arrogant loudmouth resort diver.
I see it on Scubaboard, too.
To that extent, I think DIR perpetuates its own controversy through the actions and words of a small minority of its practitioners. But because those people confirm the stereotype, they are memorable. The DIR diver next to them, who is quietly gearing up to do a good dive with his buddies, is not noticed.
We have a wonderful community of DIR divers in Seattle. Many of them are extremely generous people, who volunteer their time to help new divers, and who turn out for work parties at the local underwater parks. There is a great community of DIR divers in Monterey, who are hospitable and generous. I know, because I've met some of them. There is a warm and welcoming community of DIR divers in Southern California, too. I know, because I've referred SB beginners to them for mentoring, and heard about the results. But none of these groups can overcome the image that DIR has as a result of the few unpleasant people who alienate others, either on line or in real life. It's sad.
