Title? I don't need no stinkin' title.
If you read the article I linked to, the acknowledgment is there. Yet the author's main contention is "As a cast made up entirely of Caucasian people, many were worried that Critical Role would attempt to wade into cultures that they had no personal connections to or representatives of."Mercer has said some words about that in the critrole site:
"Marquet is a fantasy continent, and one that (like other places in Exandria) occasionally holds nuggets of inspiration from Earth cultures and locations that I have a deep appreciation for. It is a unique place with unique people and civilizations occasionally woven with touchstones that call to our real world experiences in some ways, lending a familiarity and celebrating aspects of those same languages and cultures without appropriating them. I have been and will continue to be working with professional cultural & sensitivity consultants throughout the worldbuilding and presentation of Marquet to ensure I do my best to do just that."
So because the previous settings were dominated by caucasians, it was okay. But because the new setting is not it's a problem even though the author had not watched a single episode. It's that kind of judgement, that only people with a certain ancestry are allowed to represent people from a part of the world inspired by real world culture that I find problematic. It's one thing to be concerned about culturally sensitivity, it's another to require cultural connections to me.
I'm 3-4 generations separated from my northern European ancestors. All I know about their cultures is what I've read in books or seen on screen. That's going to be true for most people after a few generations. I may have had more interest in those cultures growing up, I just don't think it gives me any special privilege or connection.
