For the record, I'm not interested in reading whether someone selected a 'yellow dress' or 'purpley pink flowers' or who picked someone up when. I'd be more interested in reading about actual intersex issues.
I am in favor of protecting the rights of everyone, but I don't even know what 'rights' you are talking about.
The intersex prevalence depends on how you define "intersex", with some definitions (those who argue "if the term intersex is to retain any meaning") making the prevalence at 0.018%, which is 2 orders of magnitude less than 2%.
Whether that invalidates her argument or not I don't know, because again, I don't know what her argument is. I was just replying to the parent poster who was surprised by a figure which I was arguing was exaggerated.
