You are being elitist. You are expecting everybody to be on your level in how they communicate. Anybody below you, you see as elitist.
Like I said earlier. These players REACT. Judge their reaction however you want, but don't ignore what they are reacting to.

Being criticized for something you did is not being flamed. Being flamed is something being said with no base behind it. Stuff like "kill yourself" is flaming. "Noob" is not, if you are having a skill issue.
