What is tha verse saying? It says exactly what it says: the people criticized in Romans were idolaters.
Romans 1:18-23, "For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of people who suppress the truth by their unrighteousness, because what can be known about God is plain to them,[an] because God has made it plain to them. For since the creation of the world his invisible attributes—his eternal power and divine nature—have been clearly seen, because they are understood through what has been made. So people are without excuse. For although they knew God, they did not glorify him as God or give him thanks, but they became futile in their thoughts and their senseless hearts were darkened. Although they claimed to be wise, they became fools and exchanged the glory of the immortal God for an image resembling mortal human beings or birds or four-footed animals or reptiles." NET
Those are the people addressed in this section of Scripture. Idolaters who turned away from God to idols.
It's trendy in these days of "gay-bashing" to condemn homosexuals based on Romans, but there are many sins listed there and I don't see those sins discussed.
