You’re right, toxicity is a real problem, but there’s nothing you can do about it except for muting and reporting toxic players. Posting on Reddit about it is like witnessing a robbery and telling the robber to stop because it’s illegal and expecting him to say „omg you’re right I’m so sorry“. It’s never gonna happen, so accept the fact that there are assholes out there. Mute them, go on with your lives and stop feeding into your unrealistic expectations.
