Description for dummies:

In the gaming world, someone toxic could be described as a hater, who chats so much shit that you wanna break your headset... Or simply mute them. This applies to PCs and consoles. Toxic gamers don't get along with anyone other than their friends, honestly no one likes them. They also usually put new players down, instead of helping them to get to know the game.

A toxic community is just full of people described above.

"It is, but besides that, console gamers are so toxic. You can't even have fun without someone telling you that you're bad"
