If Catholics did discriminate, I would be fine with that. If I wanted Catholic parents for my baby, I should get Catholic parents. Hence my going through a Catholic agency.
Let them discriminate. There are tons of options for agencies. I am a former adoption social worker and I know.
I'm evangelical, and would want evangelical parents if I was a birthmother.
I think that there is a big difference between the birth mother discriminating/saying what she would like for the adoptive parent's religion to be and the agency being discriminatory (esp one that takes public funding)....this agency would not place babies with Catholic families only b/c they were Catholic--not b/c the birth mother didn't want a Catholic family.
