A not so close reading of the text leads readers to 'side' with the Dunyain view of the world, especially early on. Its not until later books that you get a sense of how wrong the dunyain might be. I think most people have a fairly rigid perspective, so once they've cast their lot with one side, its tough to change that opinion. Or, sometimes its just too difficult to have a meaningful conversation when everyone just shrugs and says "anything is possible", so they pick a side and stick to it.
Once everything is published, things will hopefully be slightly less obscure - though I doubt many, many things will remain contentious.
