"A lot of what was said was insulting, disrespectful and rude and were negatively affecting other players."

After 12:58, the guy (jungler) responds with "i have word for you" and I reply with 14:54. I told him I would mute him because of the "don't respond to negativity with negativity".
In post-game, jungler continues to talk. I don't really remember what it was, I just wanted to move on from the game.
Question is, I don't know what part of this is negative. I wrote out what was happening in the game. I did this so that in case I got punished the reviewer can just read what happened (because they do not consider context).
