When China becomes the only superpower, and northern Europeans are barely scraping by cleaning their toilets, and most RPGs are written and played in China, and this is rationalized with a stereotype of northern Europeans as howling, illiterate savages....then we can complain about the portrayal of Vikings.
Probably to about the same reception as seen in this thread.
No, if someone portrays someone's culture inappropriately, then it is wrong and their grievances should be heard.
