I always try to say Good Game, I dont abbreviate. It is basic chess etiquette. If you can't deal with someone being a good winner that makes you a poor loser.
gg is arrogance

gl AND gg are arrogant terms. Just play chess. Forget the chatting.
That's why I like to disable chat as the first order of business in any chess.com game

gl is just stupid imo, cause chess is not a game of luck
gg is mostly ok imo, but many many times the game wasn't actually good, so it's untrue
i like to at least say hi or something like that, it feels to me like shaking hands with my opponent before the game starts, i also usually say bye or something like that in the end
Sometimes i might chat a bit, if the other person doesn't want to, s/he can tell me to stop or disable the chat. But disabling it from the beginning is a little rude i think. I've only disabled it so far for someone who told me to play faster.

I say gg when I played a game in which I didnt blunder away my pieces, played some attacks on him/her and he/she on me. If one of us wins by playing some smart moves forcing the other to lose pieces or even to mate, then that was gg to me. Even though it could probably have been much better, it was good to us :)

I ve noticed theres a big difference in CC as opposed to Live Chess.
Normally after a game 3 day per move there are exchanges gg , tough game, that was close you nearly had me if only you hadnt hung your Q etc
whereas Live Chess you play win / lose and move on with mostly not a word said
Special shout on poor winner goes out to Chess Blue , I played him at Bullet , he was down to K & 2 pawns and had been making random moves from 25 sec mark, eventually I ran out of time 2 moves before mate and was greeted with a memorable line
"hahaha loser sucker"
It made me chuckle

No. GG or Good Game is good sportsmanship, if you are winning or losing. The person who started this thread is mad because he obviously lost a game right before he posted in which his opponent posted GG. If you don't want your opponents to say GG or Good Game, then don't play chess.

As an addition to my previous comment...
GG is the digital equivalent of shaking hands and if people don't want to shake hands for whatever reason (e.g. germs, intimacy issues, etc.) than we should just let them make that choice and leave them alone.

I can understand the OP's point, but sometimes a game can be long and tense, with the winner barely holding on. If they win after 20 moves, or the loser does something stupid like blunders their rooks and queen for pawns, then gg is probably not called for. I also see "gg" a lot after I win, so I also understand this idea that he's just being a sore loser. I'd say it depends on how bad the game was.
Wow, I didn't notice how old this was until after I posted.

Uh-oh, here comes another thread...

I find saying "GG" too time-consuming and a tad old-fogeyish. I tend to go with the abbreviated, hipper, "G" or the informal "g".

Actually, it occurs to me that the dude in #1202 looks a bit like Simon Bar Sinister:
