The word of God is a sword, a weapon of defense to be used against false teachings.
From your posts it seems your god is science since you are appealing to science to interpret God's word. Science is still researching a possible genetic cause for homosexuality, but so far science has not found a true genetic link. Even Simon LeVay and Dean Hammer have pubicly stated there is no real scientific evidence to show that homosexuality is genetic.
Your use of the Bible to support your thesis is both selective and ludicrous.
Matthew 23:27-28
27 "Woe to you, scribes and Pharisees, hypocrites! For you are like whitewashed tombs which on the outside appear beautiful, but inside they are full of dead men's bones and all uncleanness. 28 "Even so you too outwardly appear righteous to men, but inwardly you are full of hypocrisy and lawlessness.
NAS
1 Corinthians 5:9-13
9 I wrote you in my letter not to associate with immoral people; 10 I did not at all mean with the immoral people of this world, or with the covetous and swindlers, or with idolaters; for then you would have to go out of the world. 11 But actually, I wrote to you not to associate with any so-called brother if he should be an immoral person, or covetous, or an idolater, or a reviler, or a drunkard, or a swindler-- not even to eat with such a one. 12 For what have I to do with judging outsiders? Do you not judge those who are within the church? 13 But those who are outside, God judges. Remove the wicked man from among yourselves. NAS
You have taken the same tactic as the Pharisees who taught extra-Biblical concepts to the Jews and Jesus was hostile to the Pharisees.
You are promoting a sin and no matter how hard you try to obfuscate God's truth by your selective use of Scripture the truth is homosexuality is sin and those who practice and promote homosexuality as acceptable to God will be judged.
