A relevant part is the following:
Much of the reporting on the issue has featured stories of children who might be denied a home if gay applicants are rejected. But that is focusing on a pebble and not noticing the boulder nearby. Boston's Catholic Charities accounts for 31 percent of the state's special-needs adoptions, those children abused, neglected, disturbed or handicapped.
More important, the state is in effect using its licensing power to bring the church to heel -- no gay adoption, no license to conduct adoptions in Massachusetts. Acting on traditional Catholic social principles -- that one father and one mother are best for children -- is defined as bias
While I don't like it, I don't see how that is religious persecution.
