I’m not sure why you seem so interested in vetting the beliefs of the author of a fantasy series. Just engage with the text.
There's a few other books that I've been unable to finish purely because I disagree with the author so much that I just can't read their work. I end up shouting at them (sometimes actually shouting at the book) so much that that forms my engagement with the text and it becomes pointless trying to read any more. At least I managed to finish Terra Ignota.
