The rules of live chess

Wow its so stupid that people think like this (I know this is satire). Especially at my noob level in bullet chess everyone seems to have brain damage.
The OP's thread logically ought to stop dead a lot of repetitive, pointless argument. Regrettably, it won't.

I like this topic as well.
Real men play on in completely lost positions to the bitter end.
Haha brilliant :D

The OP mentioned what the opponent thinks. Here is the real thing:
Offering a rematch (after losing): You want to have another game of chess against this formidable opponent.
Declining a rematch: You've got something to do in life, for example go to school/work or want to do something with your children/parents.
Accepting a rematch/Offering a rematch after winning: You believe that it was an interesting, double-edged game, and hopes for another fighting game of chess.
Resigning: You believe that even you would even against Magnus Carlsen, so there is no point in trying to hold
Not resigning: You are a real bastard
Saying "gg" at the end of a game (winner): You want to inform your opponent that you thought it was a great game. Actually you want to have a training partner, and finds your opponent perfect. You are just too shy to say it directly
Saying "gg" at the end of a game (loser): You believe that the game was good, you had half of the chances and your opponent just played slightly better. He was "lucky", but is probably a very nice person, so you want to become friends.
Offering a rematch (after losing) - Means you are insecure. You lost and want to get revenge on your opponent. Your ego has been hurt, and it's pointless to try to prove that you are better or worse than your opponent because you have ratings next to your name. Emotions trump logic.
Declining a rematch - You are a coward. You declined because of the following a.) You got lucky b.) You're afraid of your opponent c.) You have self esteem issues and like keeping a positive score (similar to offering a rematch).
Accepting a rematch/Offering a rematch after winning - You are a cocky bastard who thinks they can win again. The right move is to decline a rematch to keep emotions out of chess. There are thousands of other players on live chess that you can play, why face the same person?
Resigning - Is disrespectful to the integrity of chess and to your opponent. It denies your opponent's ability to rightfully checkmate you and defeat your kingdom. Real men play on in completely lost positions to the bitter end.
Not resigning - Is disrespectful to your opponent because it suggests that your opponent is incapable of beating you. It's also another way of saying "I'm angry that I lost, so I'm going to waste our time by playing on".
Saying "gg" at the end of a game (winner) - Only inconsiderate pretentious assholes do this. Your opponent just lost his entire kingdom and you have the nerve to call that a good game. Chess is not just a game. It's WAR. This is a very subtle way to mock your opponent.
Saying "gg" at the end of a game (loser) - You're pretending to not be angry after getting crushed. It's also a subtle invitation for a rematch. Stop trying to be overly friendly; etiquette is overrated.
