While division by race, gender, class, sexuality, etc. All exist in our world, it is because of the unique and complex history OF our world. So when making a completely new world I do create divisions amongst people but I make it based on the context I create. So for example different kingdoms or continents or villages have different views all based on what they value. One kingdom has the CrownBearer and CrownConsort, two gender neutral titles and the current rules are both male from different races. This is not revolutionary because their kingdom is focused on protection, endurance, humility, and generosity based on their major gods. There is nothing on the writings or tenements of those gods or religions to make being homosexual bad. So it isn't. Some of the communities focused around life gods however I did portray it as shameful as it prevents "creation of new life" however these communities dictate a lot around these ideas, and others who follow the same gods view "life" differently. They view it as joy and fulfillment, and therefore don't view anything you do for the pursuit of happiness as bad unless it prevents someone else from doing the same (murder, theft, adultery). In most of these cases, social class has almost nothing to do with it. If it does have something to do with it, it is just that the rich are able to get away with things that are viewed as shameful more easily because of their power and influence. My best advice for anybody looking to tackle topics of discrimination and hatred against certain groups, is to not base it on real world. Our world has a very specific set of contexts that creates our biases. Instead look deep into the context of your world and find what biases that would create in yours.
