This valid, credentialed guy disagrees with you, and without the patronizing tone. Verse 20 is not about homosexuality in any way, but about the claim that God is demonstrable in the observable world, what you call Creation. And this has not been shown true by anyone.

Romans 1:20 is a restatement of Psalm 19:1-2, which says The heavens are telling of the glory of God; and their expanse is declaring the work of His hands. Day to day pours forth speech, and night to night reveals knowledge.
Imo this is one of those moments when the Bible descends into an orgy of unsupported doctrine. And when it does that, it seriously harms the idea that this is a divine text. In all this time, we have not found one bit of repeatable natural observation that supports either the NT or OT claim.
And that sticks in the craw of any who want to assert that the Bible is correct. My opinion.
As to global warming: do i believe it is possible? Definitely. Do i think it's happening? The data say "probably" but are noisy enough that we cannot cleanly winkle out the causative agents from the first-order effects. Can I determine how much of it is anthropogenic? No. I can make educated guesses but no declarations. Do i see it as a sign of "a society not balanced with moderation?" No, since 1) I cannot find a definition for that phrase, and 2) I have no evidence that the imbalance is a cause and not an effect, if it is indeed so. I counsel against confusing cause for effect for something something that might be neither. So ... what information about me does that answer, which I consider the best honest answer i can give, tell you about me? cn
