Poorly worded; your post just had so much anger in it that I didn't take the time to phrase my reply more cautiously.
I meant enough to the point where you don't get so offended by careless people. There are a loooooot of people out there that don't think about their actions, and that's largely because they haven't had appropriate role models. How you treat them says a lot about you.
If it's something like a real life abusive boyfriend/girlfriend/whatever, then there's no reason to keep dealing with that person. But when it's a stranger who might just have had a bad day, or thought he did do pick intent (which would make your ban "intentional"), gets angry, you have choices. The more self-control you have (which frequently correlates with self-respect), the less likely you are to get into a tizzy about it. *
You're venting about it on the boards, which isn't an inherently bad response. But there are lots of people that will rant about it in champ select, and carry the negative attitude into the game. (You could have done those as well. But I'm not assuming you did.)
I've seen posts from people on the boards that say things like "you made fun of my champ choice, so I'm not going to gank/roam/peel" etc. That might be the correct game choice in some situations. If the person doesn't know how to play with your jungle Braum, ganks might be useless. If you think the person is so hotheaded that peeling is a waste of time because s/he's going to dive in and die anyway, that's reasonable. But if you want to win more than you value your pride, you won't be one of those people that makes the decision only based on pride. (Happily for your point #2, you didn't say anything about asking the whole team to report. That would be amusingly hypocritical, and it's so common to see people do that lol.)
I guess my point is more like... when I read your post, I was sad that it sounded like you were writing off those people. I mean, my reply to your post could easily have been copy/pasting your point #3. If I had a choice, I personally would prefer someone who doesn't give off the aura of being easily rage triggered. But instead I felt compelled to [awkwardly and impolitely] try to help you be more forgiving of people. Because although I might not choose anyone I get matched with, I still try to have fun with all of them unless they consistently show they're not in the mood to have fun (-> mute button).
* Referencing a point early on with position selection. People were complaining about getting positions they didn't queue for, so Riot looked into it. They said every instance they investigated was people just remembering wrong and getting angry anyway.
