Some of the best divers (albeit not tech divers) I know, male and female, have had disabilities that forced them to make accommodations. Some were from age, some were from issues they were born with. There are also several folks, one of whom is an amputee, on SB who have shared their experiences going through tech and cave training that I greatly admire and I aspire to be a diver like them, who doesn't let other people make decisions on their capabilities.
I honestly am not sure what you are trying to say here and how you are reacting to my post. I cited a diver in a group I led who needed accommodations and who got them with no problems. I fully support reasonable and appropriate accommodations, not only for diving, but for all aspects of life. In my history in education I saw how accommodations allowed students to thrive when they would have been helpless without them. For example,I once had a severely dyslexic student excel in a college level English class by using reading and writing software, when for his entire school career prior to that he had been limited to reading and writing assignments at his unaccommodated 2nd grade ability.
For my scuba example, I chose not to mention another person who was scheduled to be on a dive trip with me but had to cancel. I did not mention him because I did not get to see how his needs were accommodated--he was a paraplegic with no use of his legs, using special webbed gloves to propel himself while diving. He regularly went on dive trips where those needs were accommodated. I applaud that.
What I was tasking was where one draws the line for "reasonable and appropriate" in terms of accommodations, and I said that line varies by the needs of the dive, the nature of the dives, and ability of the operation to make the accommodations. For example, I was once on a liveaboard where the dive platform was a very small area at the bottom of steep stairs. As a result, no one on that boat had the ability to put on their fins. We all needed accommodation, and we handed our fins to a crew member on the edge of the platform and lifted our feet while he put our fins on. Another example is the elevator lift mentioned in this thread, a device that easily brings divers up to the dive deck, a device that is apparently illegal in the U.S. Without that device, how does a diver who cannot climb a ladder get on the boat? In some cases, it pretty much can't be done.
Finally, I think there is a difference between the needs for accommodations. As I mentioned earlier, I regularly exercise so that I have the strength and endurance necessary for technical diving. I contrast that with someone who does not have that strength and endurance because he or she has chosen not to do such exercise. There is a difference between someone working to overcome a handicapping condition and someone who has made a conscious choice to be feeble and have to rely on others to do something they should be able to do for themselves.
