What a sadly ignorant piece of writing. The author doesn't seem to grasp that birth certificate changes are not an attempt to alter history, but to make the certificate reflect the person's gender. When a child is adopted, the adoptive parents get a birth certificate reflecting their relationship to the child. This does not "erase" history or create some farce that the birth parents didn't exist. It's a reflection of the social reality, the same as changing the birth certificate for a transsexual.
