in answer to the OP - I don't think that adoptive parents who refuse to adopt a child because of a name would be bad parents. I actually think it is a brave thing to admit that you are rejecting a child because of his or her name. The worse thing to do when you adopt is compromise. It's not fair on the child.
When I adopted my first DC it all started with a phone call. My SW called and said that we had been informally matched with an 8 month old baby boy. My heart skipped a beat. She then said his name is ( insert name that I've seen many times on mumsnet being described as "chavy"). I admit that the best thing I could think to say to my SW was "erm interesting name!".
I phoned my husband who gave a knowing chuckle when I told him the name ( we had been through the adoption course where unusual names were discussed and we had always joked that we would be the ones to get a dodgy name!)
We googled the name , it turned out to be of scottish origin and as my family have scottish roots we decided that we could learn to love it.
I phoned my sister to give her the news - her words were "what a ghastly name!)
I phoned my Mum and she said "oh well it could have been worse".
We love our little boy more than anything in the world and I can't imagine my world without him in it but I know that if his name had been Something ridiculous hyphen Something even more ridiculous we would have had to say no. It's awful admitting that but I know that trying to live with a name that we hated would have caused problems with the bonding process. My son's name does cause people to comment as it is still fairly unusual although gaining popularity. We just say - oh yes it's a Scottish name.
At the name time that we were working with our SW she was working with another couple who had had an 18 month old placed with them. The placement had broken down because the adoptive mother was not coping. The SW had also caught the parents calling the child by a completely new name. The child was confused enough by the move to his new family without having to get used to being called a new name! The adoptive parents should have been brave enough to turn down the match with that child at the very beginning of the adoption process ( ie - during that first phone call)
I believe that the name a child is given by his birth parent is precious. My second child was not even given a name by her birth mother so her name was given to her by the nurses in the special babycare unit. It's a lovely name that could belong to a child of any class or background but I'm sure that when she is older she would have preferred to have been named by her birth mother - whatever name it was.
I know that none of what I have said provides an answer to the problem of little Chardonnay-Mai being left in care forever. I don't know what the answer is.
