I am asking that you respect people's religious beliefs and don't try to force them to accept a moral position that contradict their faith.  If you force Christian adoption agencies to place children with homosexual couples, you will force those agencies to go against their moral beliefs or shut down.  Most will likely shut down, and the people most directly affected will be the children who could otherwise have been place in good families.

By the way, although you are targeting Christian adoption agencies, there are other faiths which hold that a homosexual lifestyle is immoral - for example, Muslim and Orthodox Jew.  Please be tolerant and allow people to honor their faith.
