Sin = Sin
Two wrongs don't make a right. We have seen in the Old Testament, of the Bible, that one sin is not worse than another. So, if a generation, sex, race, etc sin like another, it may seem worse, but a sin is a sin. Different factors may make one SEEM worse than the other, but different sins are equally affective in the right environment, time, age or atmosphere. Normally, one is a product of the other.
When a ruler hath sinned, and done somewhat through ignorance against any of the commandments of the Lord his God concerning things which should not be done, and is guilty;
Society's Law acceptance has no affect on God's acceptance. God destroyed Sodom and Gomorrah for the things that its (|customs)laws accepted. If a society's laws rectified sin, God would not have been displeased with Sodom and Gomorrah. Today, laws allowing same sex marriages which seem to be a product of Sodom and Gomorrah. Some may say that God destroyed Sodom and Gomorrah because of their lack of hospitality toward His angels. If that is true, I haven't found support of it yet. But, I have found some support for anti-same sex sexuality.
Leviticus 18:21-25 (KJV)
21 And thou shalt not let any of thy seed pass through the fire to Molech, neither shalt thou profane the name of thy God: I am the Lord.
22 Thou shalt not lie with mankind, as with womankind: it is abomination.
23 Neither shalt thou lie with any beast to defile thyself therewith: neither shall any woman stand before a beast to lie down thereto: it is confusion.
24 Defile not ye yourselves in any of these things: for in all these the nations are defiled which I cast out before you:
25 And the land is defiled: therefore I do visit the iniquity thereof upon it, and the land itself vomiteth out her inhabitants.
But, everyone has free will and their own relationship with God. Again, one sin is not worse than another.
John 8:6-8 (KJV)
6 This they said, tempting him, that they might have to accuse him. But Jesus stooped down, and with his finger wrote on the ground, as though he heard them not.
7 So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her.
8 And again he stooped down, and wrote on the ground.
