Something that really doesn’t help is that although I am a gamer, I hear about how toxic many multiplayer environments are, so I never join them. I’ll only play with my real life friends, who aren’t going to call me a racial slur if I make a mistake or am honest-to-goodness bad at the game.

A toxic environment leads to droves of people who won’t tolerate it fleeing. Most people who won’t tolerate toxicity also would not perpetuate a toxic environment themselves—in other words, the toxicity drives out lots of non-toxic people. Now the proportion of toxic to non-toxic people is much more slanted towards the toxic.
