Yes, seriously, it's insulting, for several reasons. It's not constructive in any way. It doesn't tell you how to be better. It's all-encompassing. If you're a Bad GM, then you're Bad across the board.Being called bad, when you yourself recognize that you are bad, is insulting?
Heck, being called bad at something is insulting? As in something that would seriously bother people? I'll admit that it's hardly complimentary, but, insulting? Seriously? I wonder if this isn't a cultural thing. Being bad at something is pretty standard for anyone starting out in a hobby - regardless of hobby. Since when is "bad" insulting? Then again, if you're taking the interpretation that bad="malicious jerk", then, I suppose I can see why that might be insulting.
Well, the counter argument is that there are almost no bad DM's out there. That it's a TINY fraction of the hobby. That over 95% of DM's are average or better. Which I find a ridiculous assertion.
Like take your belief that bad = anyone less than 50%. Except that's a bad idea, all around, because most people aren't "bad" at all parts of GMing. I'm not good with making memorable NPCs, but I can set a scene and mood extremely well. Am I a bad GM? Another person might be great at making interesting combat encounters but suck at non-combat encounters. Would this person be a bad GM? There's a ton of skills needed to be a Good GM: rules mastery, encounter design, location design, creating interesting NPCs, playing NPCs, riddle/puzzle-making, descriptive skills, improvisational skills, leadership and diplomacy skills (for dealing with players), acting skills, note-taking, and probably a bunch more. You can even put non-skill things there like "willingness to let the game go in unexpected directions," "willingness to not include overbearing GMPCs," "willingness to abide by player lines and veils," and things like that.
When you say someone is a Bad GM, you're saying--whether you intend to or not--that they're equally bad at all of those skills. But it's rare that a GM actually is bad at all of them.
