Don't expect sinners to act like Christians and do not judge sinners by Christian standards of conduct. Sinners need to hear the gospel not how unchristian they seem.
Many Christians cannot fully embrace sanctification so we have no reason the think that sinners can be sanctified. Sodomites marry because they want to marry. Right or not in the sight of God is of little concern to them. They walk in blindness not in the light of Christ.
For the cause of Christ

Many a person has been saved by the knowledge of "how unchristian they are"
not seem, which is a part of he Gospel.
There are societal consequences when Christians abdicate their moral authority in the world which is entrusted to us by God, in this case children are seriously impacted.
It was the churches that were the main force behind the abolitionist movement, it is believers that are having an impact on abortion laws in the US. And it is actually the few faithful that are left and understand that are showing up at meetings trying to stop the indoctrination of their children.
And all these things are the Gospel in action.
