I guess you could call it lazy writing. I mean, it is. I hate the idea, for instance, that Minthara is willing to engage in relations with a surface elf. She'll even mention how she would've taken the character as a consort in Menzoberranzan, and that's ridiculous. It ignores conflict and setting and atmosphere and depth.
So. I get that it's lazy writing.
Except it's also not. From the writer's perspective, I get it. What are they supposed to do? It's a hot-button issue. While I love storytelling that allows for conflict and immersion, it's easier to just say all the characters are playersexual and avoid any arguments that might otherwise arise.
