New Gender Policy in NYC

Looks like soon in New York City, you'll be able to change the sex on your birth certificate without undergoing sexual reassignment surgery. The whole article is interesting and worth the read, but I wanted to extract these particular passages:

The change would lead to many intriguing questions: For example, would a man who becomes a woman be able to marry another man? (Probably.) Would an adoption agency be able to uncover the original sex of a proposed parent? (Not without a court order.) Would a woman who becomes a man be able to fight in combat, or play in the National Football League? (These areas have yet to be explored.)

Joann Prinzivalli, 52, a lawyer for the New York Transgender Rights Organization, a man who has lived as a woman since 2000, without surgery, said the changes amount to progress, a move away from American culture’s misguided fixation on genitals as the basis for one’s gender identity.

“It’s based on an arbitrary distinction that says there are two and only two sexes,” she said. “In reality the diversity of nature is such that there are more than just two, and people who seem to belong to one of the designated sexes may really belong to the other.”

Progress indeed.
