Benedict's opposition to homosexuality is longstanding. In 1986,
Ratzinger signed another doctrinal document declaring that ''It is
only in the marital relationship that the use of the sexual faculty
can be morally good. A person engaging in homosexual behavior
therefore acts immorally."

So here's how you do it: you condemn and oppose gay marriage. Then you
declare that anybody having sex outside matrimony is "immoral".
Therefore, homosexuality is "immoral". Case closed (along with a few
million minds).
