I'm 31... so I am older than you... not that it really matters.
And you're still making excuses. Now yours is "well games are always full of toxic crap, so it's not MY fault". Yes... yes it is. Your attitude is part of the problem. You're just shifting blame AGAIN to make it sound like you acting out or being a jerk to people is a good thing or even no big deal. People feeling this way is WHY the game is so freaking toxic. You're still in the wrong.
And I don't think you're dumb. I think you understand what I am saying PERFECTLY well and you are just choosing to deny being part of the problem because you don't actually care. Not about toxicity in the game, at least. It takes MORE effort to blast back at a rager in chat than to simply push tab and mute them... but you WANT to do it. Either you've got a temper and can't get over someone being a jerk in chat unless you respond or you just plain like having "an excuse" to start insulting and lashing out at people. Hey, I got a temper too... I get peeved at the sheet level of obnoxious bullcrap that people come out with in this game. It's why I rarely play anymore. Between tilted people screaming at each other, trolls and griefers intentionally trying to tilt people and people like you and I who feel the need to snap back when confronted with the first two... I think I can count the number of non-toxic games I've played in the last few months on one hand.
I'm telling you this because it's true. Your attitude is just as much a part of the problem as anything else. ANY time you say to yourself that it's acceptable to start arguing or insulting someone or just plain being offensive or obnoxious... you are making the game more awful for everyone. Your motives don't matter... they're wrong. You're not helping anyone by jumping in to start flaming a rager when they start going off. You're just doubling the number of people in the game who are being obnoxious by adding in yourself.
I do not care what excuses you pull out of you ass THIS time to justify it. It's not "weak" or "being a pussy" to be above arguing with some 15 year old over the internet. It's not "acceptable" if they started it. It's not okay because "Hey, the game is already super toxic". Those are all just excuses you tell yourself to avoid feeling like part of the problem. To put yourself above all the OTHER people acting just like you are. And yeah... a lot of those trolls and ragers feel just as justified as you feel you are... And that's why this game is a cesspool.
But here is the real rub... How long have we been arguing about this? We've gone back and forth for what... six posts? More? Over several days, in fact. Have I changed your mind? I doubt it. You've certainly not changed mine. And odds are, neither of us ever will. All we've done is waste our time and flood this board with ranting. At least here, we're very easy to ignore. In the game, your team is stuck hearing you unless they mute you as well... and they're TRYING to play the game in which they probably need your help while you're busy ranting and snaping at someone to "prove a point" or just to tilt them.
That's really... all I have to say. Deny it all you like my friend but you are as much if not MORE part of the toxicity problem in the game as our dear raging friend whom you're fighting with... and if you don't realize this after everything I've said here, you're either determined to stay deluded, or you're just plain thick. Either way, it's not really worth talking to you anymore.
