Well, it's hard to respond to you since you've trimmed my post to suit your response. Here's the entirety of what I said...
I'll be more direct this time. You tend to argue... not question. Specifically, you tend to "argue for a contrary position from ignorance/naivete" or "simply reject offered advice out of hand because it isn't what you want to hear."
Here's how it usually goes.
Step 1: You post something asking "Should I do X... or Y?"
Step 2: Several experienced people will reply, fairly succinctly, saying "You should do X because of thus and such reason."
Step 3: Your response to them never says "I don't understand what you mean by that" but rather your response is almost always "Well, I don't agree with you. I want to do Y!" And that argument is most often from a position of ignorance/naivete... as is abundantly evident by the fact that your responses then tend to go on and on (and on) with paragraphs and paragraphs of irrelevant and/or incorrect information and assumptions on your part.
Step 4: Experienced people (at least those with the morbid curiosity/interest in sparring with you) will point out the innacurate/irrelevant information in your response... and direct you back to choice "X"
Step 5: You then complain (over the course of a thousand words in a half-dozen paragraphs) that the experienced people who directed you back to choice "X" are picking on you, while recapitulating your position that you want to pursue "choice Y" for all the flawed reasons you used to support that choice in the first place.
If you really "don't understand X" come out and say that. Don't argue for a contrary position when you - now admittedly - don't know what you're talking about.
I dunno why this seems novel to you. Or why you are calling out one particular person.
There is a good percentage of newer diver scubaboard members that operate in this mode. They decide something (like a piece of gear) and ask, what's your opinion? When you explain why something is not a great idea, they get defensive. I bet if someone pulled up my posts from 10 years ago, they could say I was guilty myself.
I remember a few years ago when this new scooter came out - bladefish or something. All manner of people were asking how good they were (some had already decided to buy them before getting responses back). You tell em, "small battery, weak motor, cheap plastic bits" and all kinds of name calling ensues. "Elitist", "Snobbery", "DIR sheeple", so on and so forth.
More recently, there was a thread that meandered into doubles and manifolds. One of the posters was going on and on about there was nothing to manifolds and that any idiot could deduce how it works. Of course, he was wrong about every single thing he was deducing. And it turns out, he had absolutely zero experience with manifolds. None. Zero. Zilch. Nada. And after being exposed for is ignorance, he went on for days and days still arguing with his ignorance.
That's why I think scubaboard is, at times, the worst place for getting information on diving. Some of the people with the loudest opinions are actually the most ignorant. And the people who know the most express themselves in subtle ways because they know that a lot of these things have nuance and gray areas. Unfortunately, those seeking information sometimes have a hard time figuring out who knows and who doesn't.
