I find it really unpleasant to refer to the biological father as the ‘sperm donor’.
You have biological parents and adoptive parents. Calling parents ‘donors’ sanitises the betrayal of children. ‘Egg donors’ and ‘sperm donors’ are essentially parents who relinquish all responsibility for raising their children made in this way, but in my opinion, they still have a moral responsibility to the child.
Admittedly, now that women can be implanted with another woman’s egg, means that a child can have two biological mothers - the biological birth mother and the genetic biological mother, which complicates things.
But the child has the right to know and have relationships with their biological parents (unless the father is a rapist).
The only reason non- biological ‘fathers’ ever get onto birth certificates is because the woman is the one who knows who the father is and prior to dna testing, you couldn’t prove who he was. Since women can become pregnant through rape, I believe that it should remain the mother, the woman who gave birth, to determine who gets to be put on the birth certificate as father.
The wording in the title also cheapens the value of motherhood, by referring to a woman who has no biological relationship or even adoptive relationship as the ‘mom’.
The child and their rights is what is important.
