I'm sorry to be brutally honest with you here but just maybe you should look in the mirror - it seems you're one of the ones all bent out of shape because of a dive video showing people kneeling
Some have tried to explain the scope of the class but it seems anything outside of perfect form makes others a lesser diver, whether it be the form the diver shows, how the divers rig is situated or the gas he chooses to breathe.
I'm not going to go back and search for it - but somewhere 100 pages ago in talking about CO2 - someone said something about it being OK to grab a hold of a rock if you felt winded. I made a smart assed comment about it that you should come down here and learn drift diving cause you shouldn't have to grab onto things but that's all it was. Here - you touch nothing period - in a cave that you can touch stuff, heck I'm sure it's fine to sit on rocks or whatever..... It's the time and the place - either grabbing a rock is just as bad as kneeling in that situation or they're both OK - you can't have it both ways.
Instead of belittling folks - you may just get a little farther with people by adjusting your tone. You may not agree with the reasoning, the actions or methods - that's perfect, it's a big world, lot's of water and you are certainly entitled to your opinion.
