True marriage is the union of one man and one woman. Legal recognition of any other union as "marriage" undermines true marriage, and legal recognition of homosexual unions actually does homosexual persons a disfavor by encouraging them to persist in what is an objectively immoral arrangement.
"When legislation in favor of the recognition of homosexual unions is proposed for the first time in a legislative assembly, the Catholic lawmaker has a moral duty to express his opposition clearly and publicly and to vote against it. To vote in favor of a law so harmful to the common good is gravely immoral" (UHP 10).
Vatican Document On Homosexual Unions
“Homosexual unions are totally lacking in the biological and anthropological elements of marriage and family which would be the basis, on the level of reason, for granting them legal recognition. Such unions are not able to contribute in a proper way to the procreation and survival of the human race. The possibility of using recently discovered methods of artificial reproduction, beyond involving a grave lack of respect for human dignity,(15) does nothing to alter this inadequacy.”
