It's not a hypothetical, though. If you're referring to what I said, I mean. A secure person is not going to be threatened by this situation, and what anyone might say after the fact is not going to change that. If you doubt yourself after learning the birth gender or surgical history of one of your competitors, the seeds of doubt were planted long before you found yourself in this situation.
I think, though, that the question of the judges' potential bias is entirely valid. I hope they're not biased toward or against her. But I would be concerned about the possibility, were I involved in the pageant.
