One thing to note though. If she has only had sexual reassignment surgery she wont have in any way done something that would make her have any kind of advantage. It would be similar to denying someone from entering the pageant because they had ovarian cancer which resulted in them being surgically removed. I can understand supporting rules that require contestants to not have undergone cosmetic surgery. However, Sexual reassignment surgery is most definitely not cosmetic surgery despite what medical insurance companies say.
