I don't think this is prejudice…

[Dystopia]

Regardless of the fact that it is wrong to discriminate against gay parents, I believe it is wrong and against one's basic dignity to deny information regarding who we are. People have the right to know who their bio parents were, as much as they have a right to a "name" - Yes, you have the right to a name that serves as an identifier of yourself, and you can legally change it - I'm sure 100% of people here have a real life name. My GF started reading books about adoption later to understand the phases she went trough. It's not easy. Hiding things will usually not help. Many kids want to find out who bred them, it's normal. It doesn't mean they will ditch the adoptive parents and go live with their bio parents, they might even hate those people, but curiosity is normal.

Great points here. However, what if you have a woman who wants NO involvement in the child's life and does not want her information ever given to the child? What if the woman just wants to move on with her life and be left alone? If she doesn't know who fathered her child, then any medical history for the paternal side of the child is unknown. If she gives as much medical history for the maternal side as she knows, then I believe the woman has a right to be left alone - even after the child reaches 18 years of age. Not all adoptions are the same and mothers have different reasons for why they choose to give up their child.

I agree that there's important issues to consider on the parents' side, however I still believe it is wrong to not give info to people who are looking to know stuff about themselves. This isn't just about the parents, it's about kids and young adults wanting to know where they come from. In some countries, it is important to know for a variety of reasons. Yes, I agree that some parents might have nothing to do with their "children's" lives, but kids will still be curious to know and that's something every bio parent, regardless of how much they don't want it to happen, needs to face and recognize - It's one of the repercussions of having kids that you simply cannot avoid even if you absolutely loathe the idea. Plus, it's not like you will have duties if your child finds out, it's more like they'll just want to know who you are and leave you alone. Even if contact between both parties is forbidden, I am advocating merely for the right to know, not the right to have a relationship with bio parents. 

There's many reasons in many parts of the world why I would want to know who my bio parents are. Yes, there's many reasons why people make hard decisions, but there's still repercussions even if you have legally decided to completely give up and not have any kind of contact with your child. I would also want to note that people can look for others for any reason and not just parenting  - You don't have a right to have your "identity" hidden, I'm pretty sure that would cause lots of issues in many cases.
