It's funny because I agree with the comic, but as a woman, turning off voice chat and friend requests are the first things I do in a multiplayer game. I don't wanna deal with being harassed by kids a third of my age for being a woman playing games. Gamers are toxic as hell, and, like you said, plenty of communication can happen through ingame actions.

This comic got posted somewhere else, and there's a guy in there arguing with people that turning that stuff off ruins the experience for everybody else. Must've never experienced a Halo/CoD lobby, lol.
