I feel like people dont know what toxic is

If you go out of your way to be mean to someone then you are toxic, but if someone fucks up or is throwing a game then you have a right to tell them that they are deliberately throwing the game. If someone gets caught out for no reason or is misplaying so horribly then you tell them, "yo stop getting caught out you are throwing the game" and in no way shape or form is that toxic. Its not mean to tell a garbage player that he is garbage, its a fact not an opinion.
