It's not me that has anything against GMs. There's a pervasive disrespect for the time, energy, and enjoyment of GMs present in the majority of TTRPG spaces.

People love to say “it’s just a game” while stacking more and more work onto the GM’s shoulders. It’s selfishness, and often a contempt for TTRPGs in general.

The purpose of a GM isn’t completely universal across all TTRPGs that use a GM role, hell a lot of TTRPGs don’t even seem to know why they have them in the first place, but usually the purpose of a GM is to handle scenarios that the game rules don’t account for, and handle procedures that the other players are not supposed to be privy to.

Over the years, more and more responsibilities have been put on the generalized GM role: sole rules memorizor, level designer, bespoke world creator, bespoke storyteller, scheduler, host, etc.. It has morphed into being a job as much if not more so than an activity to do with your friends. GMs have been dropping like flies to “GM/DM Burnout” for a decade or more and people willing to even go near the GM role are an endangered species.

What a lot of people don’t realize is that while, yes, the rules of a TTRPG are technically changeable and nobody is going to kick down your door if you don’t play them correctly, they do serve a purpose, and that is, simplified, to produce certain outcomes of gameplay.

A game’s rules cannot account for every possible situation that may come up in something so open as a tabletop roleplaying game, and one of the strengths of TTRPGs is that when the rules don’t account for something, human players can pick up the slack. In a traditional challenge game like every edition of D&D, this slack and the privilege to pick it up is by default handed over to the GM. This is because in a traditional challenge game that slack is often only handlable with that knowledge that other players are not meant to be privy to.

Since so many people are allergic to playing anything but D&D, even when they clearly don’t want the gameplay which D&D is geared to produce, this privilege instead becomes a curse for the GM. All of the scenarios and characters that D&D(or any TTRPG) is simply not intended to be built to accommodate are seen as “the slack for the GM to pick up” instead of “things that are outside the scope of the game.” It’s going to a coffee shop and telling the barista, who hasn’t trained in pizza, to make you a pizza. “A good barista could make it work, this is a food vendor so I’m supposed to be served the food i order,” even though the barista isn’t trained to make pizza, and the coffee shop does not stock the necessary ingredients for it.

Except the GM isn’t even getting paid minimum wage, they’re voluntarily taking on the most high-responsibility role of a group activity for you. Even if you do convince them through the shame of thousands of “a good GM could make it work, a good GM never says no to what a player wants” posts to make you a pizza, it won’t be a good pizza and it won’t go well with the other items on the menu. And even if it turns out to be a good pizza (because bad pizza is still usually pretty good pizza, not because it’s actually a good pizza) it won’t really be the coffee shop’s pizza, it’s the barista’s pizza. Once you go far enough, creating so much slack for the GM to pick up, you aren’t playing D&D anymore, you’re playing The GM. After a certain point the GM is doing way more work than the rules.
