Should gay couples have the same adoption rights as straight couples?

LGBT adoption is the adoption of children by lesbian, gay, bisexual and transgender (LGBT) persons. This may be in the form of a joint adoption by a same-sex couple, adoption by one partner of a same-sex couple of the other's biological child (step-child adoption) and adoption by a single LGBT person. Joint adoption by same-sex couples is legal in 25 countries. Opponents of LGBT adoption question whether same-sex couples have the ability to be adequate parents while other opponents question whether natural law implies that children of adoption possess a natural right to be raised by heterosexual parents. Since constitutions and statutes usually fail to address the adoption rights of LGBT persons, judicial decisions often determine whether they can serve as parents either individually or as couples.
