Error #1: "We are our own gods."
We are not gods, which means we don't establish our own morality. True moral rules exist independently of us, because there is a God, and we aren't God.
If moral rules exist as merely a product of the culture, then in theory the majority culture could agree to kill all homosexuals and the LBGTQ movement would have no moral authority by which to persuade the majority not to slaughter them. LBGTQ moral philosophy could, in theory, bring about the execution of all homosexuals. It's like a double-edged sword that can be turned back upon them and wielded without remorse.
If we applied LBGTQ moral theory to everything, society would be destroyed. The philosophical roots of the pro-homosexuality movement are atheism, or pantheism, or polytheism, all three of which are false. Human beings have never had the right to create their own personal moralitities. And the very worst people we know think that way. We have all been victimized by people who believe that.
Error #2: Humans are good.
The reason we feel certain desires from childhood is because we;'re all sinners from childhood. Some people have felt an overpowering pleasure about lying, or stealing, since childhood. Some people have felt an overpowering pleasure in violence since childhood. Some people have felt an instinctive animosity toward blacks since childhood.
This happens because we're born sinners from the womb. The human race is born evil. There is something radically wrong with us. So the fact that someone has felt same-sex attraction since childhood doesn't validate anything.
Since when are our feelings something we should all act on? I feel a lot of bad things, every day, but I don't act on them.
Error #3: Homosexuality is healthy.
There are millions of men who have died, who would be alive and well today if they hadn't engaged in homosexual sin. If homosexuality was universal, it would kill off the human race. It is a life-style of disease, depredation, victimization, and death.
Error #4: People can't stop being homosexual.
If homosexuality was encoded in our DNA, no one could stop, any more than we could will our eyes to become a different color. But people do stop being homosexuals, all the time. They especially stop when they are born-again by the Spirit of God. Over time, the Lord enables them to re-learn and receive who and what God made them. They root out the lying humanistic philosophy embedded into their thoughts, and take every thought of theirs captive to the obedience of Christ. The Spirit of god lends His power to the renewal process. It might take years, but anyone can stop being homosexual, through the power of Jesus Christ.
