Yea… Also previously in this thread someone did ask if series are blindly following the book - they don't. I didn't read the book but some things mentioned in discussion are presented differently in series. Should I care what a bookwriter says about series based on the book? If I cared, I'd probably never play The Witcher 3 because the bookwriter hates what developers did to his "gem". He can hate it as much as he wants, the game is still a masterpiece. Again IMO.
I guess that was me. However all I asked was if the racism depicted in the book was present in the TV series. There was no request to ask if the series was "blindly" following the book. And actually, whether you want to believe it or not, my take in that regards is very similar to what a Hollywood director once stated about this topic: If the audience wants an exact duplicate of the book, then read the book.
