Well, the hope would be that it is not a rant.
Instead, the hope is that it is an explanation of why this is a problem, in a way that those who have not realized that it is a problem could truly grok--understand at an intuitive, gut level, rather than what is often dismissed (in other terms) as "highfalutin' nonsense" or the like. Further, my intent is not to say "HOW DARE YOU HAVE BADWRONGFUN", it's to point out an unfortunately pervasive problematic behavior that many do not realize is a problem, because it is subtle and its effects only manifest over long stretches of time. Ideally, I would further provide specific, useful advice, strategies, and tools to not only avert such a problem in a given DM's own games, but to help DMs work with players who have already been "trained" by such problematic DMing, so those players can un-learn the bad, unhelpful coping/defense mechanisms they've built up, and thus working more productively with DMs and groups in the future.
I know this is a perennial problem for DMs, and this is a forum frequented more by DMs than by players. Presumably, someone who could benefit from it would see it. Ideally, it would also attract others who can add their own hints, tips, etc., or provide their own experiences and how they resolved similar issues. Speaking more practically (some might say cynically), it will also invite a score or two of people who fundamentally reject the premise, deny that this is ever a problem, question whether I am smearing their preferences, etc., but I prefer to focus on the positive hope rather than the cynical-but-probable.
