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.
Well, yes, that is correct if you define “gay” by the behavior. On the other hand, if you define it as “experiencing sexual attraction to the same sex,” then you can talk about “chastity for gay people” in the same terms as “chastity for all people.”
Among those who regularly write on this topic, there is no agreement regarding using the term “gay.”
