I don't think this is prejudice…

A part of me does think it's important to at least document somewhere who both the biological parents are. If I were to go through surrogacy or gay adoption, I'd want my kids to have the option of knowing who their biological mother/parents are if they wanted to know or if the donor/surrogate mother wanted to be involved in the upbringing. I think a lot of adopted kids probably do, naturally, wonder about their biological parents, and I think it's unfair to with-hold that information from them if they want to know about them so much.

That's the only, possible, ground I will give anti-gay adoption people. It's not "homophobic" to allow the biological surrogate mother to be involved with the kid if she wants to be, and I think it's ethically right to document the real parents for the child's sake.

If some places treat adoption differently it's entirely fair for gay parents to have the same rights as straight parents.

That shouldn't be up to debate I think.

In my country, the ID card and birth certificate list 99% of times biological parents. There's lots of legal reasons for it. Citizenship, inheritance, the legal right to KNOW your parents, etc - It's really hard to get away without doing it, because assuming you are born in child labor, like it seems everyone is (unless we are already cloning humans which would be interesting), you will be registered right after the birth and you cannot legally refuse to register yourself as a mother, and need to provide the father's name adequately - Unless there's some sort of legal exception, like if it is fertilization in vitro, or if you were raped and got pregnant as a result - You may have a legal exemption - But in most cases no. Personally, I think it's normal for kids to feel curious - My GF had the teenage phase most adopted kids have of wanting to know her mom and wanting to leave the house and live with her bio mom - That's normal and it's complicated to be an adopted kid in some phases of life.
