I guess Sue and her husband just don't understand what it can mean to someone to identify their birth family, even somewhat distantly related members. Sometimes even especially if their birth parents are deceased. I know that when my mum dies (my dad is deceased already), I will be very glad that I have siblings and cousins still.
Everyone here is interested in their family origins and their ancestors, and enjoys finding out who they were and researching their lives. Some can't imagine what it is like not to know where to begin in that search.
If I'm keen to find out who my greatx6 grandparents were and where they lived and what kind of lives they had, why would an adopted person not be just as keen to learn about the people from whom they descend?
I can't imagine not helping someone do that if I were asked. I have only done YDNA testing of two male relatives, to try to solve a couple of genealogical mysteries, but if someone searching for birth family found a match with them, I would gladly do autosomal testing myself if it would help.
Even if an adoptee isn't able to find out exactly who their birth father and mother were, they can sometimes identify someone who is closely enough related to say that they share, say, great-grandparents. For someone interested in genealogy, that is important information for research. For someone who wants to know their family, that can be as personally important, depending on the people who are found, as finding a parent or sibling.
I have helped many people over the years, on the internet, find the parent they never knew, and many have found that they have an extended family who welcomes them. I don't know why using DNA to do that would seem any different from using the electoral roll.
(Sue/Dean1: there should be a 'notify' button to click at the bottom of the list of messages. Mine says 'unnotify' so I presume I clicked 'notify' at some time.)
