Villager segregation per book type can lead to ingame case of certain race discrimination

So basically separating "good" and "bad" trades depending on the community may lead to conflicts and also lead to players specifically prioritasing one "race" of the villagers due to better and more useful books which directly leads to ingame racism. Noticing previous change with skins, mojang goes into preventing any discrimination in their game, while having a true and meaningful reason to segregate different types of villagers seems a litte bit wrong.
Also Savanna and Taiga villagers may be reffered to african and nordic nations, and while these villagers sell the least useful books, this may also be counted as an insult
