Exactly, did no one read the original thread?
- A player wants their character to be vegan? Fine. IRL there are religions that have similar practices, so having a god/goddess have a similar requirement in a fantasy RPG shouldn’t even cause an eyeblink.
- The character continually proselytes and advocates for veganism in-game, including to the PCs and most/all of NPCs they come across? Could be fun if done well, could become really annoying really quickly if not done well.
- An irl player wants the DM to change the gaming world in an already-running game so that everything in the world is vegan? Not fine. Go design/run your own game if that’s what you want to do.
Following the same train of thought but in meatspace:
- A player is vegan and wants to bring vegan snacks and share them with the other players? Fine.
- A player is vegan and demands that no one else eat any non-vegan snacks at the table? Not fine. You do you, but don’t force anyone else to conform to your belief system.
My reply to the original thread on reddit was pretty simple: sometimes the DM just needs to say “sorry, but I don’t think you’re a good fit for our game/group.”
Actually, just doing that would solve >90% of problems posted on /r/rpghorrorstories.
