Form a biblical point of view all sex outside of marriage is an equal perversion. Dividing it into fornication, masturbation, pederasty, adultery, etc., is a modern point of view.
Seeing homosex as a particularly perverse manifestation of idolatry is not new. In Romans 1 the Holy Spirit is the one who focuses on that, showing that as idolatry replaces the true and living God with a false god, so souls left the God-designed and ordained sexual mate for one that was unnatural.
Heterosexual relations are wrong when outside a valid marriage, whereas homoeroticism, like idolatry, is unconditionally wrong.
While all sin is sin, and one sin will damn you, the ultimate one being rejecting Christ, when a person or calls of persons insists a practice is not a sin, then that error it must be dealt with.
