And it's pretty clear that when Paul mentions it in Romans, he's using homosexuality as an illustration of total revolt against God - total, persistent, active rebellion against one's Creator. I know that this view has lost favor among recent revisionist exegetes (as I'm sure you're itching to point out), but I hold them in the same contempt that I do revisionist historians -- they are almost agenda-driven rather than striving to be more objective (again, I know you're itching to say that objectivity is impossible - I disagree, especially wrt to God's Truth) in discerning and accepting that which has previously been discerned.
Sin is, certainly, sin, and all sin kills. Paul, and thus the Holy Spirit, seemed to have a particular reason for hammering the point home so hard using the example of unrepentant homosexuality. We may not like it, but that lessens neither the import, nor the validity of the point.
Paul talks about same-sex behaviors -- I'm not going to argue against that. However, it is only one illustration of those whom God has given over (Rom 1:24, 26 & 28). 1:29-31 is a long list of sins that come from the same "giving over" that God did earlier:
"filled with all wickedness, evil, greed, depravity, full of envy, murder, strife, deceit, meanness; gossipers, slanderers, God-haters, insolent, arrogant, boastful, inventers of evil deeds, disobedient to parents, senseless, untrustworthy, inhuman, unmerciful."
If we are guilty of any of those defects, we are in the same category as those whom God gave over to disgraceful passion in v. 26.
