Brother,
I think it is an example of the "lovers of self", etc. that Paul discusses in 2 Timothy 3. That list is particularly directed at the "last days" condition of people.
As far as I can tell, this is not optional. This is mandatory: Satan MUST assault the image of God. It is his rebellious nature and it is his overarching goal.
Follow me on this for a sec.
1. Man is God's highest creation. (Gen. 1, 2; Ps. 8:4, 5; Ephesians 2:1-10)
2. Man is made in God's image. (Gen. 1, 2)
3. God is triune; He is a community within Himself, needing no other. (Gen. 1, 2; John 1:1-18; Acts 17:25)
4. Man's creation was not good with him being alone, without community; therefore, God made it "good" when He made "male and female" "in His image" and "joined [them] together" as "one flesh". (Gen. 1, 2)
5. Therefore, marriage and the one-flesh relationship is God's first and lasting revelation of His nature as a community of persons.
6. Satan is God's enemy who works in creation through schemes. (2 Cor. 2:11, Matthew 4:1-11). Those schemes include the harming of people. (Luke 11:13-16)
7. Satan's goal is to prevent any hope of any of God's image-bearers being placed in the Gospel. (Luke 8:11-12)
8. One scheme of Satan is to snatch away hope that has been planted in those who may otherwise believe. (Luke 8)
9. Another scheme of Satan is to prevent the great mass of people from ever seeing the truth by using distortion, deception and thus "blinding" the world to the truth of the gospel. (2 Cor. 4:3-4)
10. Satan is particularly adept at using man's most basic, essential nature against him. We see this in the Garden when Eve is tempted, we see it in the wilderness when Jesus is tempted.
11. Just as eating food and gaining knowledge are inherent qualities we possess, so are self-awareness & self-nurture part of who we are. "No man hates his own flesh, but nourishes it and cherishes it." (Eph. 5:29)
12. Sexuality is part of who we are created to be. "[A] man shall cleave unto his wife...". See, also, 1 Cor. 7:2, 3.
13. Therefore, as part of his last days strategy to mar the image of God in the view of man, and to prevent his hope being placed in the truth, and even snatching away the hope of some who would otherwise believe, Satan will mar and distort the true image of God in the eyes of men as he blinds them to the truth. He can most effectively do this by perverting human understanding of our sexuality as it drives to the heart of who we are created to be and who God is in us.
It is my own personal view that Satan MUST do this now. That it is the perfect time, for Satan's schematic needs, to do this now on a global scale. It is not unreasonable to think so since time is short (getting shorter, too).
Consider, too, in this light, 1 Timothy 4:
Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons, 2 through the insincerity of liars whose consciences are seared, 3 who forbid marriage and require abstinence from foods that God created to be received with thanksgiving by those who believe and know the truth. 4 For everything created by God is good, and nothing is to be rejected if it is received with thanksgiving, 5 for it is made holy by the word of God and prayer.
"Forbid marriage" includes hindering or denying it. It isn't sexual abstinence; it is a blocking of that which is good, just like "abstinence from foods" is not about starvation but blocking a life of thankful partaking of that which God blesses for those who "believe and know the truth".
(I know homosexuals now "marry", but it is not marriage as God defines it, it is not the union of two people in one flesh in reflection of His own nature. That's the point of Satan's scheme, right?)
So, yes, in my understanding of Scripture, homosexual conduct and approval of it are symptomatic of the time of the end.
