I feel like this community, or most online communities, have never participated in any kind of activity where competition matters. Whether that's school, work, sports, or anything else for that matter.

It sounds like you're the one who hasn't participated in damn near anything outside of online video games, because if you take your attitude to any real-world, team-based exercise, you'd be kicked off any team or fired from any position without even an explanation.

Shit, your attitude isn't even appropriate for retail work. The only reason anyone puts up with your attitude in-game is because the game is independently entertaining and ultimately people can mute you and still reap the benefit of your mechanical skill.
