This is a change in topic, but I don't see how it relevant.
No, it isn't a change in topic.
Bohandas said, "I'd like to address a double-standard that seems to occur on a lot of threads like this:
How come people have a problem with Orcs being predisposed to evil, but they don't have a problem with Beholders, Demons, Mind-Flayers, Red Dragons, Vargouilles, Ghouls, Shadows, Vampires, Hell Hounds, etc. etc. etc?"
The "people" in question aren't characters in the game. They are the real-world people writing in threads. So, we are talking about the biases of real-world people, not in game people.
Then, the fact we humans do tend to identify more with things we recognize as more close to ourselves does come into play. Whether someone in a myth chose to lay with a bull is not material.
