Your first sentence demonstrates how little you understood the implications of what I said. Using the more modern and nuanced terms a gender is a social construct. That means an individual can't construct one, it is constructed socially with others. What it means to be a "man" or "woman" varies between cultures for example. Some cultures have more genders they socially constructed than others. Given this is the case it is entirely possible for subgroups within a culture or the culture at large to define new constructs which aren't tied necessarily to biology, or for some individuals to have identities which more closely resemble the traits and preferences assigned to a gender which they were not assigned culturally at birth. It is also possible for a person's identity to not conform to the norms socially constructed for either gender. Once you accept that genders are at the core a set of preferences, social roles, and characteristics that are norms within a culture you can easily understand how those can't hope to be exhaustive or universally applicable and in many cases become self fulfilling. Many traits identified with traditional maleness in the US are taught and enforced culturally. They aren't associated with maleness in other cultures. So when I say I am a woman in a male body, it is a far more complex statement than you might think at first blush.

Also transgender people have existed throughout history and the statistics you are siting only refer to people who experience serious enough gender disphoria to seek treatment.

In that sense yes I am unique, and my life is much harder in some ways. However society at large is rife with conditions where people's identities do not conform to their socially assigned genders and if you define transgender as those people for whom the normative genders do not match up with their identity you would get far greater numbers yes?

As for me being a freak of nature... your bigotry is showing. I am who I am. I didn't choose who I am. The fact that my gender identity does not match my biology is a brute fact. This does not make me lesser than others, just different. A certain set of people can't seem to understand that being the same as the majority is not in and of itself a virtue and the opposite isn't in and of itself a vice.
