While you make a good counterpoint, you hide an important part of my argument by citing paragraphs 1 and 4 rather than 2 and 4:
I think I missed this because honestly I don't see the mockery here. Yes, it pokes fun at gamer elitism but I don't see it doing it in a mean-spirited way. This is an admonition to check your elitism at the door here. I probably need that admonition every once in awhile, personally,Paragraph 4 snipes at the content; paragraph 2 snipes at the players.
Break it out when you don’t feel like dealing with complicated plots, fussy social interactions, and so on. The results won’t be refined. They might not even be “real roleplaying” (whatever that is). But they’ll be fun!
Snobbery isn't the same as taste. I think snobbery is more of a lazy shortcut around actually deploying discretion and critical analysis in art. So snobbery about "real roleplaying" isn't actually helpful to the hobby, especially if it stands in the way of fun.
