When designing a medieval style Tabletop RPG, which style has proven more popular: historically accurate social views, or modern views?

In the wake of recent events, I’ve become honestly curious as to what sales figures and/or other social media metrics might reveal about our shifting views regarding what is or is not popular and acceptable in tabletop role playing games.

Medieval beliefs and views (generically speaking) tended towards black and white, strongly religious (not always in a positive way), and varying degrees of xenophobia or tolerance towards different cultures and practices.

Modern social views eschew many of the views and beliefs common during those historical times.

Thus when designing a game based on a historical (medieval) period which might include such sensitive historically accurate topics such as plague, racism, social and religious discrimination, slavery, and other challenging subject matters, what metrics exists that reveal which is preferred today?

Thus when designing a medieval style Tabletop RPG, which style has proven more popular by the numbers: historically accurate social views, or historically inaccurate but more acceptable modern social views?
