WotC has been trying to remove racial tensions in the setting (personally for the worse) so what you are seeing is normal.
That being said, Larian isn’t making much attempt to make encounters grounded or real as your examples show. You’ll just have to suspend your disbelief more and more.
Whats the purpose of playing a drow or gith then when the entire game should fully neglect all it brings along? We could then just play a human hue brown or elf hued black.
