I've been wondering what makes someone toxic in-game so I'm here asking for your opinions.
Let's look at this situation: a player is calling another enemy player "bad" with valid reasons and he doesn't call him any other names or doesn't curse at him such as "noob, tra*h, idiot" etc. but only calls the player "bad". The player is polite by calling him only "bad" while giving reasons for that at the same time. Also, the player doesn't give up in the game and plays normally and helping his team. For example "you're bad for such and such reasons".
So the question is: is it really toxic behaviour or just criticism/opinion?
