A quote from the first link:

The whole idea of worldbuilding is a bad idea about the world as much as it is a bad idea about fiction. It’s a secularised, narcissised version of the fundamentalist Christian view that the world’s a watch & God’s the watchmaker. It reveals the bad old underpinnings of the humanist stance. It centralises the author, who hands down her mechanical toy to a complaisant audience (which rarely thinks to ask itself if language can deliver on any of the representational promises it is assumed to make), as a little god. And it flatters everyone further into the illusions of anthropocentric demiurgy which have already brought the real world to the edge of ecological disaster.

What a load of crap. I mean, I've read a lot of pretentious literary garbage in my time, but this takes the cake. Dismissing an entire genre? Equating it with outdated and irrelevant religious dogma and insulting both writers and readers in the same belittling breath? Assuming all readers behave in a certain way? Fetishizing the belletristic poison of the privileged class? Claiming that Tolkein caused global warming? Talk about bias! The writer isn't even criticizing the fantasy genre or the act of wordlbuilding as it is practiced, but is instead performing a kind of philosophical masturbation with a straw man. Anyone who reads and believes this malarkey should take a hard look at why. Just saying.

Upon reflection: Please forgive me. I was overcome by the urge to punch this writer in the face. It has (mostly) passed. I promise that if anyone want to have a rational discussion about this, I can do so---as long as you don't claim that world-building causes global warming.
