Do you think God's laws and statutes are designed to harm homosexuals ? Do you really think he hated homosexuals so much he created laws regarding immorality that were designed to make their lives miserable ?
God's law is designed to point out man's sin. You might want to substitute the word "murderer" or "robber" for your word homosexuals. No difference. They are all sins and in need of Christ's forgiveness. The law was not designed to make lives miserable but to bring people to Christ seeking his forgiveness and living in the light of God's love. God loves the sinner but He also hates the sin.
God's laws are not harmful but in fact are instructions to us on how to live the best life we can. The Hebrews looked at the law as a special gift from God. Early Christians looked at the law as affirmation that God loves us.
The instruction that we either have sex in marriage or we remain celibate is God's advise on how to make our lives the best they can be. The same holds true for murder and thief. God's laws are not intended to make the life of the murdered or thief worse, They are intended to tell the murderer or thief or homosexual that his life is better if he loves God with all his heart, mind and soul and if he refrains from murder, theft or sexual immorality.
