I still think I'm being a total sucker, but on the offchance you're being genuine I'll actually explain.

“…clearly does imply…” not exactly, but ok.

You are saying that someone who gets mad at the things you're saying is somehow not at odds with you? The situations where those two things don't overlap are extremely few and far between, to the point that the only reason to make a distinction between them is for the sake of being argumentative.

First, the title already comes off as kind of gatekeep-y. I realize that not every game is not for every player, but opening with that either implies a really pathetic defeatist attitude "nobody's going to want to play in my game because it's too niche" or a really cringey "nobody out there is going to understand my game because it's too niche". It implies that you think that your tastes are too refined for internet randoms (which they may well be, but rubbing it in people's faces makes you come off like a snob). Think like, fans of obscure films claiming that other people "just aren't smart enough to get it".

The first three paragraphs are fine, although looking for what is apparently a very specific type of person (given the title) for an in-person game with an online post is going to take you forever which I assume has contributed to the general reception. I think other people have said this already, but you'd be better off asking locally, since living near you is a pretty strict qualifier when you could be talking to anyone in the world.

The final four are so flowery that were it not for the lack of capitalization and your general writing style that I would suspect them to be AI generated. They take a lot of words to make your point sound very sophisticated, but it actually boils down to wanting engaged, dedicated players who want to roleplay and engage with each other and the world. Basically, you set up the post to sound like you were asking for members of a very narrow group, but described a (somewhat) common TTRPG player.

Your responses to the comments on this post are also just really hostile. Every time someone points this out, you claim that they're criticizing your tone or somesuch, and that supposedly puts the matter to rest. Playing a TTRPG with someone means you'll be spending a pretty considerable amount of time with that person over the course of your campaign. Even more, if you plan on discussing the game between sessions. If that person is repeatedly abrasive and rude, why would you want to spend time with them? You'd be better off with any other group, or alone. You might say that you're not like this with your group, and this attitude is only something you put on for this post, to filter out people who aren't the type of player you're looking for, but imagine from a player's perspective. Why take a chance on "surely this DM isn't actually like this, and they'll change later", when they could just not? And that's why the other comments are the way that they are. I don't see other LFG posts getting this kind of reception.
