Why Are Secular Progressives So Threatened by the Christian's View of Homosexual Behavior?

Why do the the secular progressives feel so threatened when homosexual behavior is called a sin by Christians? Is this sin unique among sins? The recent fury by the Hollywood crowd over Kirk Cameron's honest answer to a journalist's question got me to thinking about this. 

For thousands of years the church has declared many various things as sinful; practices that are in direct rebellion against the Creator. These are acts that God Himself revealed to men as opposing his Lordship. The church has always declared the sinfulness of sex outside the covenant of marriage (before and after marriage), the sinfulness of idol worship, greed, hatred, pride and arrogance, self-righteousness, murder and many more. And the largest proportion of these are directed toward the church's own sin. You can see this every morning in our prayers and every Sunday (in confessional churches) during the corporate confession of sin where we remind ourselves that we are sinners and do so by then naming specific sins we ourselves are all guilty of ... and the very grace in the gospel constantly reminds that we are no better than others (this is such an easy sin for all of us to fall into), and we also remind ourselves that but for the grace and mercy of God in Jesus Christ alone would would have no hope at all. We confess daily that if we based our ability to please God and earn eternal life on our own broken sinful lives, that none of us would make it, since we all justly deserve God's wrath. Humanity, therefore, needs a Savior because it is in slavery to sin and bent on rebellion against the only one who can deliver us. None of us are immune from sin and our personal sin is not above the sin of the gay person. We are all equally damned without God's grace. 

When we tell others that something they are doing is sinful behavior in the eyes of God it is not because we hate them or think we are better than them. On the contrary, it is a call from other sinners like them to escape their slave-master and flee to Jesus Christ, the one who lived the life we should have lived and, in our place, died the death we justly deserve. None of us are born free. Only Christ can set us free.  Continue at Reformation Theology
