As I said: medieval setting implies intollerance and prejudice.
Actually, no, it doesn't. That's a pure historical fallacy with no basis in any historical fact. It's a false assumption that, more than anything else, has traditionally been used either to make historical reports glorify their 'much more enlightened' modern way, OR by bigots to justify their bigotry. Please do some research before you parrot stuff like that; it's harmful to honest discussions.
Settings like running man, tributes of panem, zombie apocalypse, medieval settings etc. are not chosen because they necessarily imply conflicts or prejudice but because we *want* to depict conflicts in a movie/book/game and need a "pretense" for that
If it's not a cultural or ethnic conflict, it might simply be a religious one - for example a new deity called the 'absolute' whose followers seek to wipe out the disbelievers
Then you don't have Drow Elves vs High Elves anymore, but instead religion A vs religion B.
By the way, it's completely fine to criticize Western, 'enlightened' societies. But it should also be clear that literally every single country in the world is more intolerant, more discriminatory and more racist than the West. Just to keep the popular bashing of Western societies a little bit in line.
