Per Trump's executive order, people are now classified as to gender in the following way:
(d) “Female” means a person belonging, at conception, to the sex that produces the large reproductive cell.
(e) “Male” means a person belonging, at conception, to the sex that produces the small reproductive cell.
So if someone, due to a congenital issue, can produce neither reproductive cell, they are now officially "none" when it comes to gender.
Will there be a "none" option on new government forms? Or will non-gendered people just leave that blank?
