"Toxicity in gaming" is a term coined by people that had weak banter, weak gaming skills, weak social ability.
If you can't handle my venomous shit talk, then you don't deserve to play the same game as me. Go back to The Sims. You're not ready to exist in my world.
And do you know why I talk so much trash? Because of studies like this. Because I know it gets into a person's head, it upsets them, it breaks them down spiritually and that makes them easier to dismantle and destroy and win. I'm not some fool, there's me vs. you and I don't like losing. Don't like it? Get better and win and then push your moral shit but until then you're going to sit there and fumble through trying to ignore me while I send you tilting so hard you will live the next twenty minutes of your life in vertigo.
