As an adoptive parent, I can positively state that having a private Catholic adoption agency made it possible for my husband and me to adopt our daughter.  Our baby's birth mother was specifically looking for a Catholic agency and a Catholic couple, if she was going to make an adoption plan, at all.  Being able to access a faith-based private agency was critical for all the parties involved.

If you remove agencies' abilities to place children based upon their deeply-held religious beliefs and traditions, you will effectively close down all the faith-based agencies.  They will not be able to function under such restrictions.  Their ability to decide what types of adoptions to manage is not discrimination; these are religiously-held convictions to which churches and agencies are entitled under law,

Adoption will suffer if you remove private adoption agencies' rights to decide what type of families they wish to assist.  This type of legislation would result in an increase in abortion or children being raised in poverty by young mothers who would have been glad to make an adoption plan, had there been a nearby agency to help them.
