Other posters supporting his request listed a few reasons for wanting this: they don't like the animations of their toon; they created the character as the opposite sex of themselves and the novelty has worn off; they want to be the opposite sex in the game for some perceived advantage.

Or does tinkering with a cornerstone of human identity make this a bad idea? Tell us what you think. And leave out any derogatory or insulting remarks. Those will get immediately deleted.
