This topic is very delicate as many may have sensitive opinions about these issues. One thing that comes to mind is, when it comes to the Drow/Dark Elves, it seems to be a common theme in fantasy settings for them to be seen in a different light among other races. For example, in Elder Scrolls, the Dark Elves are arrogant and racist as well, especially against Argonians who they used to keep as slaves. This theme for dark elves has existed for a very, very, very long time and I believe that when this theme was created there was no hidden agenda as these issues where not as blatant hundreds of years ago. Each race at that time practically lived in their own region. We have to be careful how we connect some of these issues to fantasy settings.
