And the legal precedent is strong for this - except in the cases where it pertains to abortion. Body autonomy is a strongly held value of our country - unless it relates to women.
I'm sure it's not a popular stance, but it's one I've held since I was a teenager. A man does not become a father until he starts taking care of a child who has been born. Before that, he's a sperm donor. In my opinion, he has no paternal rights until the baby is born. Period. End of story.
