dtgreene: How is this any worse than having a character who told you dark elves are abominations or something similarly racist? That sort of thing happens all the time in Baldur's Gate 2, and it's even good aligned characters who say that. (Just try recruiting Viconia with Aerie and Keldorn in the party.)
jepsen1977: You don't seem to understand drow society - drow as a race are considered evil by DnD alignment system with only a few exceptions (like Drizzt and Zaknafain). Drow society is also matriarchal and all drow females are above males. This is also why drow males can be mages but females can't because all the females are clerics of the Spider Queen and magic is seen to be beneath females.
Having these racials tensions in the Forgotten Realms is not "racist" as you suggest but instead gives depth to the setting and characters. To inject your own politics and morals into stories is always a bad idea just like being able to identify with or BE the main character can be bad. It's okay for stories to have unsympathetic characters that we can't relate to and all we need to ask is: is it a fair representation of that character to make it a good story.
How can racial tensions not be racist?
In my opinion, you can't keep your own morals, your own ideas out of stories. That's what writing is all about, to convey views of the world. They may differ from your own, but they always contain bits and pieces of the person who created them, of the society they were created in and much more.
True, you can have unsympathetic characters. But what makes them good characters is not their rule as bad guys per se. Good villains are complex, they have issues, may they be of a moral nature, psychological, driven by fear or passions or whatever else.
So please don't tell me that moral our politics or social issues have no place in games or stories or any other work of art. They do. They are integral to it.
