Chastity for “gay” people is exactly the same as chastity for “straight” people. It calls for sexual continence except for acts in the procreative form in the context of the sacrament of matrimony. It requires striving for purity of heart and mind and intention toward all people as a reflection of divine love.
What I’m trying to say is that but “gay” people are only “gay” when they are living a lifestyle of deviant sex.
The deviant sex is the very thing which defines their “gay” identity.
