Is there anything legitimately wrong with gatekeeping?

Telling people to learn about the hobby they want to get into before getting into it is gatekeeping

You write like a NPC

No, people should be able to embrace a set standard for their entertainment without someone who really doesn't care about it all that much demanding that it's made to cater to them.

No. It's important to remind EOPs they're subhuman.

What exactly is not having a Yas Forums and what does having or not having an account have to do whether you write like a redditor or not?

That's fucking gay. If someone wants to play a game they should be able to play a game without some fag telling them they need to behave a certain way to do so. It's a fucking game.

I mean, if they want to be a part of some group/community revolving around said game then I can understand, but otherwise that's some sad fucking shit.
