Again -- and I reread the article just to be sure -- this is a /very generous/ reading of Wyatt's words.
Honestly, I tend to run a pretty funny game. I draw a lot of inspiration from Terry Pratchett and Hajime Kanzaka. I still think Wyatt is way out of line.
I'm simply amazed how someone could look at a situation where you have a 3 foot, squashed-faced, hairy, green goblin with bad teeth and ratty clothes trying to
push around a 6 foot human, getting all up into his grill, acting as bullyish as possible... and *not* see the inherent humor in that. I mean c'mon... do you see the "tough guys" Munchkins of the Lollypop Guild in The Wizard of Oz and not laugh your ass off?
It's all about who they are and how they act... and when you combine how goblins are
traditionally run with how they look and behave... we're going to find it darkly amusing more often than not.
To NOT have that happen... you would need to
change how goblins are described, and how they behave and how they act as part of the goblinoid hierarchy. Now sure, maybe that's what you all are advocating... that goblins get written up to become just as dangerous and jerkish as orcs, hobgoblins, and gnolls... but the thing is, we already HAVE orcs, hobgoblins, and gnolls. We don't need more. We need
different types of humanoids to encounter.
ALL types of humanoids. And yes... some humanoids that at first glance we'd think of as a potential joke. Ones where we think "Pff! Pushover! Stupid, little, rat-face gits!". That is, UNTIL a dozen more show up and they all gang up and pigpile on you, ripping you limb from limb. Then, it's not so funny anymore.
But at least it wasn't the same "badass" dangerous humanoid archtype and encounter we get as with all the other humanoids. If you don't want "funny" humanoids... you've got another dozen different choices in the monster manual already to use instead.
