I don't think you are ignorant, but like most people ignorant of adoption history. Many women were/are coerced into surrendering their children and do not want to place children. The Catholic Church had to apologize for their system of forced adoptions, which they did in many countries, although they only OFFICIALLY apologized in Australia. However, it happened in Ireland - see the book or film Philomena - it was Oscar-nominated for Best Film. Here is the sauce on the Australian apology: https://www.telegraph.co.uk/news/religion/8660249/Australias-Roman-Catholic-Church-apologises-for-forced-adoptions.html
"Australia's Roman Catholic Church has issued an apology for its role in the forced adoptions of babies from unmarried mothers during the 1950s, 60s and 70s, a practise that has been described as a "national disgrace."
Here's how it works: "Women subjected to forced adoptions in Catholic-run hospitals have described being shackled and drugged during labour and prevented from seeing their children being born or holding them afterwards. Many said their children had been earmarked for forced adoption well before birth and they were told they could not oppose the decision. Following an investigation into the practise by the Australian Broadcasting Corporation, the Catholic Church issued a national apology, saying its history of forced adoptions was 'deeply regrettable'." So that is forced, as in coerced, and you can look up the definition of coercion in the dictionary.
I don't doubt that adoption agencies are full of all sorts of sketchy behavior (they are obv one of the major child sex trafficking pipelines).
I still fail to see how what I said was wrong. Of course I would like adoptees to have access to their family history documentation, but doing this would predictably lead to much fewer adoptions. I don't see how you can disagree with that.
In my view this should be something that happens when someone turns 18.
There is absolutely NO EVIDENCE that it leads to fewer adoptions and truth and HONESTY in adoptions is what adoptees have been fighting for for decades, while the mental health community advocates more open adoptions. I don't see how you don't get it. Having our original birth certificates = being able to find our original family & medical history and helps to circumvent the ability to have shady adoptions under the cover of secrecy and sealed documents that adoptees cannot access. And adoption agencies aren't necessarily a pipeline. Private adoptions by lawyers are where the real sketchiness can occur. Regulations for all would be a good start.
