You do realize that swings both ways right? After all, you never asked me what my experience or level of knowledge is. You just presumed that you know more than me. And then, when presented with actual facts, you doubled down and refused to accept any information that didn't fit with your experience and then pretended that I was the one being unreasonable.
Frankly, that mirrors almost perfectly how discussions about gaming goes. Someone presumes that their experience is the only possible one, that anyone who didn't have the same experiences is either stupid or lying, and that the conclusion that the person has come to is the only possible right conclusion. Typically this is followed with a complete refusal to actually examine those experiences and try to find any sort of root cause.
Perfect example is the claim that older versions of D&D were this endless grind fest of dead PC's. I've been repeatedly, and quite vocally, told that I could not possibly have been playing right unless I had this string of dead PC's during play. Or, another good example is the pace of character advancement in earlier D&D. You'll hear people absolutely insist that character advancement in AD&D as glacially slow compared to later D&D. But, then, when we start looking at the xp awards in published adventures, and suddenly, characters are bumping levels pretty quickly. 3-5 sessions seems to be the norm - with about a year of play to get to name level or so. This is backed up by actual text in the 1e DMG where Gygax actually straight up says that this was the expected pace of advancement.
But, apparently, all of that doesn't matter. You'll hear how AD&D players apparently took months of play to gain a single level, all the while dying like flies and losing their equipment constantly.
Then, when we start actually drilling down into why these things happened in games, it often turns out that the poster had a shopping list of house rules that gave these results.
So, yeah, this is exactly what the OP's rant is getting at. Posters who have absolutely decided that their conclusions are the only possible truth out there and a flat refusal to even discuss the possibility of different experiences.
