People declining takebacks in casual games for mouse slips

This is just unfair and arrogant. I mostly play casual chess, and I mouse slip rarely. When I do however, my opponent refuses to accept when I explain to them in chat, sometimes even start swearing at me in a foreign language. I agree takebacks shouldn't be in rated games, but it's casual, come on.

Why do you think chess players are going to be nice people? generally they aint, they have big ego's as a person and like to be sadistic in games

You shouldn't hold other people accountable for your mistakes.

In chess it’s like in life: actions have consequences. We need to make mistakes and we need to feel the little sting from time to time to learn and grow.

Besides: if a casual game should be meaningless enough for your opponent to accept your takeback request, the game should also be meaningless enough for you to just accept your mistake. Just start another game. Life is good ;)

I've never requested or expected an opponent to give me a takeback in any game under any circumstances. It wouldn't even occur to me.

It's my mistake and I am responsible. Same rules for them. Expecting my opponent to accommodate my mistake just seems like an entitlement that I personally would find embarrassing.

@scuffi
He isnt talking about a mistake in the game he is talking about a mouseslip error

I agree with the others: You need to accept your mistakes and go on with them. Everyone else does. Mouseslips are part of the game, for everyone. They happen to all of us. Learning to accept one's mistakes is part of what it takes to build discipline - and ultimately, to become successful: Top sportsmen are hard on themselves and don't expect second chances or special treatment when they make mistakes.
Also, another aspect is that it's bad etiquette telling people you made a mistake - it downplays their achievement by suggesting they won due to your errors.
Just accept your errors, take the "little sting" as Scuffi mentions, be a good sportsman, learn to handle your mouse properly, and focus on perfecting your own game, so the mistakes happen less and less.

I call a mouseslip a mistake. What do you call it?

a mouse-slip

#1 There is no rule, no law which states "You must accept take-backs in casual chess games", therefore, it is not unfair.
#2 Just because a game is casual doesn't mean that the opponent owes you anything, or needs to do you favours.'
#3 If you ask your opponent a question, aka, request a take-back, and they say "no", which they have every moral and legal right to do, then that is your own fault. Not theirs.
