That's just how it is. If someone has to be that much of a hateful person that they need to mock another player's performance, I will simply make them lose. It's just the only option I care to take. It isn't something I should get banned for either. Toxic behavior breeds more toxic behavior, and I believe after people start losing enough games, they will eventually figure it out. Be nice to other players and they can turn around even the worst losing lane.
