Originally I wanted to address respect between all players, but is seems this topic has erupted into a generational argument. I implore you all to realize this game has existed before your great grandmothers. We are all keeping this venerable game alive. I understand "GG" Good Game may have lost it's meaning. So let's look for a solution. How do you say "I appreciate your game." with no judgement or malice?
Etiquette at the end of a game "Good Game"

Dear Sir or Madam,
I wish to tender my most heartfelt gratitude regarding the competition in which we have both been engaged. My satisfaction and respect for your prowess and sportsmanship are presently palpable. I earnestly wish you the best of luck in your future contests, and hope this message finds you well.
Sincerely,
Your opponent

Or, if you want to be a reasonable person, you'll just not chat at all. Because even carefully worded sincerity can be mistaken as ridicule by insecure morons.
It seems to me that it's usually beginners who want to chat. Experienced players don't bother with it.

I'm an older fellow, and I don't think it's necessarily a generational thing. My very first "long" time control game here was a couple weeks ago, and I played a college student or grad student, and we had a very nice post-mortem chat after the game.

Older people seem to misunderstand the place of "gg," was the point... because they don't play popular online games... and for good reason. The games are childish and the user base is full of kids. It's not marketed, designed, or accepting of them.

For example there was a recent post about fortnite.
Ever heard of it?
Telling a kid you've never heard of fortnite is like telling an old person you've never heard of the Beatles or Elvis... it's unthinkable.

Actually, I have heard of Fortnite for several months now. My young son wants me to get it for him, and I said no, it's too addicting.

Personally, I wouldn't mind if my opponent wouldn't say "Good game" (especially after I checkmated him or made resign inside 10 moves). It's not being disrespectful, at least for me. I don't always need reassurance.

I turned chat "on" for friends only to avoid verbal abuse and to shut nosy opponents up.
I always have it off. There are multiple methods of communication available to us here. Leaving your chat on and then playing Chess against random people from around the globe - and then being outraged when you receive verbal abuse - is just point blank silly.

omg people here are such whiners. Why don't u go and complain to chess.com staff to put in an option where if activated automatically makes ur opponents account say gg in the chat without them typing it so u can get the satisfaction of seeing a "GG". SMH
Is there a way to auto-post "good game" or "thanks for playing" at conclusion, whether by checkmate or timing out? I sometimes forget to post the comment, but other times my opponent leaves too quickly for me to do so.

CoffeeAnd420.....what a sad and bitter outlook on life! May you find all the happiness you deserve!
?? Obviously you're extremely out of touch. I'm not unhappy, I have plenty of things that bring me joy in life, and I value my relationships with other human beings. That said: I'm a realist. I prefer to call the world as it is and then begin addressing it rather than just whitewash it with hopeful fantasy while the problems fester further. I wish you the best in attaining education, understanding, and wisdom in your lifetime.
Damn! You must be ancient if you were born in a world where etiquette didn't exist!
