Actually I am amazed at this thread and how it has evolved. What I hoped would be a civil discussion rooted in logic and critical thinking/analysis, has in part a degree of unwelcomed bravado and testosterone.
I am beginning to think it is a cave diving thing.
I am an occasional participant in threads in Caver Divers Forum. Since most of those threads deal with world-wide water conservation efforts, I am only interested in a fraction of the topics being discussed. Lately I have been very frustrated by the fact that every thread in which I am interested and have even participated has degenerated into ridiculous off topic idiocy. For example, the thread on the recent death in Ginnie Springs, in which a diver died trying to exit on a dive in which he did not bring enough gas to deal with potential emergencies, ended after someone made the comment that no one has ever died from bringing too much gas. Now, does anyone not know what the person meant by that? Well, it turned into a total mess when people started to talk about some incident when someone had trouble handling multiple tanks, etc. It was simply inane and had absolutely nothing to do with the thread. That pretty much ended all meaningful discussion.
In another thread dealing with buoyancy issues, I mentioned the obvious fact that all technical divers, including cave divers, have to begin their dives significantly overweighted because of all the gas they have to carry. Again, does anyone not know what that means? But no, we can't have a meaningful discussion about the actual topic because people had to quibble over the use of the word "overweighted." Post after post went on and on about how if you need all of that weight, then you aren't really "overweighted." That ended the discussion. No one apparently wanted to participate after that.
I could give other examples, but I think you get the idea.
It reminds me of something that was written in the grammar book that was required in my Freshman English class in college more than 45 years ago. It said something like, "If someone asks "Can I go to the bathroom?" only an English teacher would not know what that means." For some reason, some people have a need to pounce on things like that and ignore the actual topic of discussion, and for some reason those people seem to thrive in the cave diving commuity.
