I know for a fact that I'm inherently toxic, and it's something I'm trying to avoid being before I'm temp banned or chat restricted because of it. Most of the time I literally say nothing for the entire game and communicate with pings because I'm focused on winning my lane or looking for ganks. The times I DO talk, unfortunately I'm probably arguing with someone.
I can keep a level head sometimes, but when the xXxTriKSh0tCoDPrO420xXx tries to speak at any point in the game and insists they're right about something obviously wrong, talking just for the sake of talking, I lose my sh*t instantly.
