Isha...interesting. I'll have to do some more reading about your theory. However, I think Alice-V made a great point: to the best of my limited knowledge, genetics and hereditary traits are not necessarily the same. We're all quick to agree that all of our physical traits result from genetic expression. Why is it such a stretch to extrapolate this to our mental and personality traits? One other thing: you and several others have made the argument that, "There's no history in my family of crossdressing or transgenderism, so therefore the answer can't be hereditary." Really? I successfully concealed this from every person on the planet for three decades or more. Many of you have done the same. You're telling me that you don't think that your ancestors might have been able to achieve the same thing, and taken their secret to the grave? Particularly in a much more conservative era? Come on.
