I know it must be hard for the biological parents AYG and I'm glad times have changed now so it is not so frowned upon and people are much less likely to be "forced" to give up their children (and I appreciate it must be hard for the parents to have done so)
But, from my point of view, I was raised by a loving family, I have no memories of anything but that family so in my mind my real parents are total strangers.
don't get me wrong, there is of course a curiosity there about what I might have been or how I might have ended up had things been different, but I doubt I could have had it a lot better than I did so I am happy to stay as I am. (incidentally, my adoptive parents have always been very open with me about it and always told me from a young age that they would support me and help me if I ever did want to find my real parents)
