Ah you mean how the media went nuts a few years ago because a "man" was having a baby. When, in reality, it was a F > M TG.
I don't see the point of it on a census because it's more of an emotional state of being. If I'm looking for hard data then I don't want feels mixed up in my information.
And honestly, no one has ever said it to me, the way you just did. Usually it comes across as a "I think, therefore I am" statement of fact. Which, it isn't. Unless we can change that troublesome chromosome, even the new lab grown vaginas wont change your biological sex.
No issues with the transgendered, just the way bio-sex appears to be asserted as fact.
However, I'm willing to be wrong on the way I'm receiving.
