But when you start turning everything that isn't human into vile monsters you start losing that ability to suspend disbelief unless you believe in the fantasy of racial supremacy in real life.
Elves, Protoss, angels are depicted as exceptionally good and honorable. Zerg, Orcs and Chuthulu Illithids are depicted as evil, vicious and actually supremacist.
The statement that all non-humans would be depicted as 'vile monsters' is simply not true.
where different races are fundamentally different from one another in behavior.
Why would I play a game in which every species is exactly the same in biology and behavior? Why would I play a game in which there is no conflict? There would be nothing to learn, nothing to discuss?
You obviously do not realize that fantasy races are a mirror of humanity. Elves, Protoss and angels are the 'perfect' humans, the way we would like to be. Orcs are the evil, vicious humans, the way we would not like to be.
The OP is upset because racism isn't ingrained into Faerun - which means that the actual game structure doesn't reflect racist values where different races are fundamentally different from one another in behavior.
If you were honestly interested in prejudice or intolerance, you would never complain about fantasy RPGs. Or burn Harry Potter books on Twitter :O Or complain about the depiction of Orcs in Lord of the Rings.
You simply desperately search for some kind of 'microaggression' to accuse random movies, games or books of being 'intolerant'. And your true aim is to force the developers to promote your preferred ideology.
In truth, you guys simply are not 'antiracist' at all. If your were, you would be out in the streets and protest against actually intolerant groups - starting, by the way, with actually dangerous people like Yusra Khogali, IS & Co.
