Humbles point is well taken. Does God inflict corporate punishment on those who are innocent? Israel struggled with this idea throughout Scripture. It’s not nearly as simple as you make it out to be.
God does sometimes punish all. While some of us did not choose it, nether did we effectively fight it.
People use the example of God promising to not destroy Sodom and Gomorrah for the sake of 10 righteous. But He was going to punish them until the request was made. Turns out there were not that many. In a deeper theological sense, no one is righteous. As Christians, we are COUNTED as righteous because of Christ’s righteousness. That does not let us off the hook here and now. I think the purpose of the Sodom and Gomorrah example was to show God’s judgment on that specific vile sin. Clearly there were other sins in the world. This was most vile. Homosexuality is an affront to God’s fundamental design of humanity. Not unforgivable for those who repent, but still.
In Romans 1 we see that the presence of it in a society is itself a judgment. It is a judgment for not acknowledging God and not being thankful, etc. So it is itself a judgment. How much more judgment we face will depend on if we repent.
Those who did not promote it are still little by little giving into it. See the boy scouts. See the various Christian schools and even churches. See the politicians who refuse to stand against it. The government will use its power to enforce submission and acceptance. Many will cave.
There is the issue of ultimate judgment of each individual. In that sense we are all guilty before God and in need of a Savior. In another sense, God is the Ruler of the Universe does punish nations and people in the here and now according to His Providence. These things overlap. We should never feel so confident that God will not choose to judge our nation just because some of us are Christian. That view puts Scriptural truths at odds with each other. They are not at odds. They overlap. We should be first concerned about our own soul but that does not mean we do not share responsibility for the actions of our government in a constitutional republic where we the people are the government.
