Some assert Apostle Paul's prohibitions on homosexuality are abusive homosexual relationships not consensual same-sex relationships?

Question: Some scholars have asserted that Paul's writings about homosexuality are actually about abusive homosexual relationships (i.e., rape, prostitution, etc.). Isn't it the case that what Paul says does not apply to consensual same-sex relationships?

Due to the work of Robert Gagnon and many other biblical scholars, we know that this was not the case.' Secular historians of the Roman Empire also record clear examples of consensual, adult same-sex relationships in the Greco-Roman world. Paul knew exactly what he was condemning. Christians need to remember, given the doctrine of the divine inspiration of Scripture, that when Paul condemns something, the Holy Spirit condemns it as well. When we cite Paul, we cite the Holy Spirit. 

Romans 1 and 1 Corinthians 5 present a very sophisticated argument for the sinfulness of same-sex acts and same-sex relationships. In 1 Corinthians 5, Paul demonstrates an undeniable belief in the sinfulness of both the passive and the active participants involved in the act of male same-sex intercourse. This is stunning given that the secular view in the ancient world only viewed the passive participant as the shameful one. In the ancient world, the passive partner in male homosexual intercourse was shameful in taking the role of a woman, but the active partner continued to act in an essentially masculine way. 

Paul, on the other hand, by grounding his argument in Leviticus 18, demonstrated that both partners were engaged in a sinful act and under the threat of divine condemnation.
