There are always posts about how people don't want to be insulted, how they shouldn't be flamed, etc... I agree with this; however, while you're trying to have fun other people are trying to have fun too. Some people, myself included, have more fun when winning. Thus, if your bad play is influencing that, it's ruining my enjoyment just like me flaming you would ruin your enjoyment.
Thus, if you expect me not to flame you, I expect you to apologize and state that you're having a bad game. It happens, we all have them, but own up to your actions. If you want to be respected, I want to be respected too.
