Nope, didn't say anything about only listening to authorities. I said if you aren't even skimming the game, who cares about your take on it? How did you hop from there to some sort of gate-keeping argument?
No one's forcing you to discuss games you know essentially nothing about, even if they come up in a thread. If a discussion veers into references to RuneQuest, I don't feel the urge to express the merits and flaws of a game I've never looked at beyond the cover, even if I suspect I might have something general to say about BRP or Stafford. I don't have context. I got nothing. I shut up. It's not hard, and no one's slamming any gates in my face.
But here's the thing—if I'm constantly in discussions where something like Apocalypse World comes up, and I'm really interested in these discussions (more than just to defend my one beloved game), you know what I'd do instead of spending time writing undercooked guesses about PbtA? I'd just read Apocalypse World. It's not long. I mean, must be a reason the darned thing keeps coming up, right?
Imagine someone who refuses to spend a couple hours watching Goodfellas but keeps spending time, over the course of years, posting about how it's just another mafia movie, no big deal, etc. I absolutely do not want to hear that person's take on Goodfellas—and possibly on any other movie, tbh, if they're just conjuring up uninformed opinions out of thin air.
