When transphobes talk about the ultimate sanctity of birth certificates, how they only describe factual information present from birth, I think about that a lot.
How the hell two old-ass Italians who could barely even fuck had a Puerto Rican baby I'll never know.
When I was adopted, they changed my name AND the parents listed on my birth certificate.
Meanwhile, a lot of places still want you to cut your guts open and show them documentation that you did it if you want to alter your birth certificate to list the correct gender.
