I think the entire philosophy behind DIR is sound. I won't go that route, though. It is really too structured for my style of diving in most cases. I have taken bits and pieces of the gear configuration and try to dive in synch with those DIR folks that I do dive with on occasion.
I agree with Lynn that no one in this thread has indicated they are superior divers (they may think that - but so do all kinds of divers think they are superior - so what?), and come across as exclusive.
I'm not sure why this bad attitude is still perpetuated by the non-DIR groups. But I can give some insight to why it was in the early stages. First of all, the name fries a lot of folks. Then, there used to be a real cult-like attitude in the early days by the "graduates" of fundies. I didn't take the class, but I suspect there was some of that stressed in the class itself.
However, since it has gone mainstream and the early reaction was so loud and harsh by the majority of other divers, they have obviously softened their stance, even renaming to GUE vs DIR.
So, I think it is time to move on from the bitterness. Can't we all just get along (not you, though, JeffG)?
