This type of behavior just lowers you to their level. In my opinion you look worse honestly. You are essentially willing to actively and consciously expend energy to aggravate and provoke another person when the alternative action would be to simply walk away and move on with your life. This is a form of bullying. The person who is raging at the team and wants to surrender may be a jerk but has surrendered to their own weakness for anger. You made a conscious decision for revenge essentially. This is shallow.
Furthermore this type of behavior only continues to provoke more negative behavior. If you have ever wanted the community to be move positive but act in such a manner then you have no right to complain as you are actively contributing to the negative atmosphere. People want everyone else to change but take no personal responsibility for their own actions. If you want change you have to understand that the negativity as to stop somewhere. Someone has to stand up and be the bigger person and say "No, I'm not going to respond, I'm not going to sink to their level, I'm not going to let them get under my skin and affect my behavior". That's what's really happening too, you are letting this person win, you are letting them affect your behavior and change how you would have acted without their presence. They won, they got under your skin, they provoked you to retaliation which is what every rager wants most even if it angers them more.
Your confession (which is an exceptionally accurate term as a confession involves something you should be ashamed of having done) is not unique and I believe is a very common sentiment among a large part of the LOL community. That does not make it acceptable. It shows your own weakness and lack of emotional restraint and strength. Learn to be more self controlled, have more self respect, don't let these people change who you are. And if you can't do that, please just use the mute button.
