Some of us are actually trying to help you by pointing out differences between your perception and reality.
There is a saying: "You don't know what you don't know, and what you don't know can kill you."
Many of us here have been in the same shoes. When I started diving, there were only a few others in the area that had even any remote sort of tech training. I had to develop buddies that had the same interests and goals here locally, and we networked to make friends and dive buddies in the areas we were interested in diving.
My local dive shop thinks we are nuts because we'd rather drive 13 hours to spend a weekend diving caves instead of take a two hour flight to Mexico.
If your goal is tech diving you'll need to develop a thick skin because there will always be someone who finds fault of what you're doing and how you're doing it.
You'll need to learn to listen to those that have been there, done that, bought the t-shirt. Take bits and peices from each and every person you come in contact with and let their experience be a guide.
And don't blindly accept an answer at face value. If someone can't substantiate the reasoning behind why they do something a certain way, if they are just a follower and they do it because they were told to do it that way, then that is NOT the person you want to be learning from.
Free advice, take it for what it's worth.
