While some points here I agree with, the irony is 99% of this goes against Wrong Organ's own beliefs on their OWN game. Wrong Organ likes the silly content, the jokes, and yes there are inappropriate jokes to make (the example here is way out of line), but Wrong Organ themselves actually LIKE people who make silly content with the characters and don't act like the game HAS to be taken seriously all of the time.
I do not understand what OP has against roleplayers but not artists. Hey, OP, you do realize artists can make just as many inappropriate jokes! And roleplay is not inherently a joke or "just being silly", right? Roleplay can be a way to explore complex characters, broaden horizons, build empathy, and perhaps explore one's own feelings towards their own circumstances or traumas! Yes, that INCLUDES ask blogs! Just like art can be serious, so can writing. Just like roleplaying can be inappropriate, so can art.
There's also nothing inherently wrong with making jokes or shitposts about a "serious" work. Hell, look at Wrong Organ themselves. They've released many shitposts with their characters and worked with creators like Joetastic to make some funny bits. Jokes do not inherently take away from a work when they are in "good taste" (for a lack of a better term). They are a way for people to explore characters they love and have grown attached to. If one joke or shitpost causes you to see the work as less serious or less meaningful, you need to look internally.
It's not okay to act like everyone must enjoy a work the same way you do. People have different interests, different talents, and different ways of expressing their love for a work. Honing in on roleplay (and, by extension, writers) for problematic parts while insisting that artists could do no wrong is vile itself. You are a part of the toxicity. Yes, speak out about problematic questions and roleplay prompts! Speak out about problematic stories! But one particular art form is not the cause of the fandom's problems. It's okay for you to not like it, but it's childish itself to tell people to "grow up", call them vile, and stop doing THEIR art because you don't like it.
TL;DR: Call out problematic components, not art forms as a whole. Also, being silly is okay.
