Great Post, IronSteam! Lots of wisdom.
Why do some players immediately resign the moment they lose the momentum? Is it ego? Pride? Shame?

I sent Coolout a very sweet text and he texted me back, with an angry, bitter text, making it clear he has NO intention of returning to the chess forums. ☮️, Coolout.
I hope all the best for him but let’s continue to have lively discussions, agreeing to disagree, with no anger, no malice, and no attacks on another participant’s point of view. Here’s to ♟ and all of us ♟ nerds who ❤️ the game!

"I give up on chess and its communities". Let's be honest here - your chess and communities didn't extend beyond a few months of this website and a few channels on YouTube.

In response to CooloutAC’s comment re: my post, exasperation is not defined as “lack of mental fortitude”, nor does exasperation (or“lack of mental fortitude”)lead to emotional weakness. Stick to commenting on chess, buddy, and leave the psychology to the experts. Just saying.🧐
It is. just like stamina is not only physical. Its mental as well. But I guess maybe i'm lying to myself. Maybe this game really is just a math equation and depends on nothing more then memory and there is nothing sporting about it. I like the idea of the game, but maybe its just a fantasy. Its hard to argue against people resigning as soon as they make a mistake in their line. Because at the highest levels thats all this game is unfortunately. "skills" are really not the correct term for whats required to play this game. Don't worry optimissed you won't be annoyed by me anymore. I give up on chess and its communities.
I'm sure most people here would agree "chess communities" are not the problem. There can be certain people within those communities that are a problem though. Since some people have a difficult time relating to others, maybe a change of pace is a good idea. Maybe instead of always trying to argue something, find a place where that doesn't happen so much. Maybe instead of complaining about chess players, go to where there are actually chess players.
Find a local club, play some over the board chess. Find some like minded people. I think you might find the "chess community" isn't as bad as you imagine.

Man, Chess players are offended by anything. Personally, I'll resign when I reckon it's very unlikely that I'll win. Then I choose to spend my time playing a new game. Sometimes I like to see how it ends and play until mate. Apparently you are the party pooper in both conditions.

Would you say that most chess players are introverts?
I don't think I'm qualified to answer that. In my opinion, I think most chess players are pretty representative of the general population. All kinds of different people.
I play chess regularly with only about a half dozen people, I don't go to a chess club or play in tournaments. Of the people I play chess with, none are really introverts.

This is the reason (in my opinion) why you're feeling so defeated at the moment - because you seem compelled, often, to "argue against" things.
How about, instead of arguing against members ... connect with them, instead?
Obviously, everyone here loves chess, to some degree (otherwise, they wouldn't have joined a chess site). Find common views, instead of declaring opposing viewpoints.
Seek to understand, instead of seeking to rebut.
My wife likes to say, "You teach people how to treat you", and I believe that holds true online, just as much as it does IRL.
If you're argumentative, declarative, authoritative... you're teaching people that they should treat you the same way.
If you speak condescendingly to others, they'll do the same back to you. If you speak kindly to others, they'll speak kindly to you.
For the most part (barring some exceptions), social interaction is like a mirror ...
Also, I don't view chess as just a "math equation", or nothing more than memory. I consider myself somewhat poor at both memory and math, though I do enjoy chess.
I view chess as more of a "puzzle" kind of game. Or even, perhaps, like a thinking version of a martial art. Memory plays a role, but it's certainly not everything. A lot of chess comes down to looking ahead, searching for weaknesses, looking for ways to attack those weaknesses (or defend your own), seeing your opponent's ideas clash against yours ... Sometimes you come out triumphant. Sometimes you get wrecked ...
