It's the go-to excuse for personal irresponsibility. We don't accept this excuse for social problems having to do with anger, thievery, or lying, so we shouldn't accept it for sex, either. Even if we inherit a strong natural inclination toward an emotion or a behavior, or if we learn it from our up-bringing, or if we are driven into a negative direction of life by abuse, we still have free wills, and we still owe it to God and other people to act right.
"I was born this way" -- what does that have to do with right or wrong?
Right is still right, and wrong is still wrong, regardless of our feelings. Right and wrong are objective and don't change, because there is a God who is real and who never changes. The idea that right and wrong is a Chinese buffet leads to violence and chaos, with every person doing whatever's right in their own eyes and victimizing others in the process.
"I was born this way" -- but God didn't do it. There is something radically wrong with every human soul, but that isn't how God made us. God created the human race good. God intended this world to be a good place. But Jesus Christ taught that there was a first, original man, and that man, by rebelling, spiritually cut us off from God's love. That first man poisoned human nature at the root. When we experience feelings of rage, immorality, deceit, or greed, that is not who we were meant to be. Those feelings are typical, but they are notnormal.
You were born lacking an inner connection to God's love, which is the one sure cure for all selfish, evil feelings. God can re-connect with you, and He wants to. Rather than excusing ourselves with the phrase, "But I was born this way", we should ask God to re-connect with us through his son, Jesus Christ. What will happen is that you will be spiritually re-born, in a new way. You won't become perfect, but you will begin the journey of conquering yourself, through the power of God's love.
