"Much - MUCH - more worrying is the prevalent view on this board that newbs are alone. Tough ****, **** off, work it out yourself."
Very nice attitude....... "Newb's" seem to be viewed with disdain and disgust. Well, I guess flying is (sadly) different than diving afterall. This is equivalent in flying to seeing a new pilot auger in and saying tough cr*p! shoulda worked out that cross wind for themself. Thanks for the bitter taste in my mouth, really appreciate knowing how much people new to the sport are valued. Ugh.
It's not that newbs are on their own, it's that ultimately, in diving as in about everything else, you are responsible for your own safety. That doesn't mean that when possible, people won't go out of their way to help you, they will. But if you do something incredibly stupid, there's a good chance that even if you are diving with the best diver on earth, there is little they will be able to do to save you from yourself.
That's what the point is. While the DM in this case certainly did a lot of stupid things, ultimately, nobody had to follow him. Yes this should not happen, but it's not just the DM's responsibility to ensure you safety, it's ultimately your own too. The DM certainly violated lots of standards, but regardless, people followed him.
I can certainly understand why you have a bad taste in your mouth about the dive industry, but I also think you really don't understand the realities here. PADI and all the other certification agencies exist to make money. They have standards and regulations not to prevent someone from doing something stupid but to protect themselves when someone does.
I am honestly grateful for my instructor because he didn't try to blow smoke up my ass about safety. He made sure we all knew that the laws of physics that govern diving are absolute and don't like to be played with. Diving can be dangerous, but it's really only as dangerous as we choose to make it.
