This is just simply a lack of self awareness. I do not think they developer actually put a lot of thought into those rules. He just needed rules and came up with some. I also do not blame him for a lack of self awareness because it is down-right rare for people to have any real sense of self-awareness. I mean, how many of us really know, as in having taken an inventory of our beliefs, what it is we believe? Then having done that, examined our beliefs and actually understand why we believe what we do?
In the game world, this is rampantly obvious. I have long since noticed how it is very difficult to create an ugly woman, and how difficult, if not impossible, to create a beautiful male avatar.
I really think things are going a bit too far with the politically correct police.
