Roleplaying games have had some rocky history too, there's a much larger space for non-white non-cishet players and designers these days but that hasn't always been the case. Early dnd was pretty reactionary and echoes of it are still felt (ed greenwood's forgotten realms being the default setting is a part of this). The whole white feudal Europe but also magic, where you take the law into your own hands and theres institutionalized racism really appeals to certain people.

Recently wizards wanted to change racial stat modifiers to be less of a racist dogwhistle and more about culture or individual aptitude and there has been a huge outcry about it (orcs no longer having a negative Int in character creation rubs racists the wrong way for some reason). Its definitely changing a bit with how many lgbtq+ and poc are entering the space/being recognized as having always been here, but there's still lots of weird fascists and bigots hanging around.
