how to deal with toxic players

its hard since lyte is like hitler and wont let you defend yourself or say anything basically but here is what you can think in your head. someone was calling me delusional in a game today. This player was diamond 5 only played one champion had a 50% win rate with it and fed in this normal game where he raged all game long and eventually just RQ'd. He names off some egotistical stuff like "ive gotten to diamond 3 times i know what im talking about" "your team even agrees with me you are delusional" (only his duo agreed with him hes plat 5 go figure his duo agrees l0l) All you have to do is some research. I look him up he fed this game can only play one champion and hardly, alot of games played afk's in normals and rq's. Then we look at me , 70% win rates higher elo than him did fairly well that game 7-3. And at the end you can obviously see that a majority of the time the ragers are just worse players who rage because they either do bad or their way of thinking is wrong and they are mad. So just dont say anything and laugh because they will continue to be bad dont help them by arguing they wont listen to you anyways because you are right. And if they are better see if they have some good reason why try to learn but a majority of the time the feeding rager is the toxic bad one.
