Children need loving homes. The shape of those homes is irrelevant as long as the people in them are willing to give love and raise children responsibly, regardless of whether that home consists of single parents, same-sex parents, or any other "non-traditional" configuration of responsible, consenting adults. If these "non-traditional" families are willing to adopt or foster children, they should have the same chance that any other family would get. Discrimination only makes the present problems worse.
