We do know what's right and what's wrong though. The bible is our guide to life. It tells us exactly right from wrong, sin is black and white.
Genesis 19:4-5, 11-13, 24 Before they had gone to bed, all the men from every part of the city of Sodom — both young and old — surrounded the house. [5] They called to Lot, “Where are the men who came to you tonight? Bring them out to us so that we can have SEX WITH THEM.” ... [11] Then [the messengers from God] struck the men who were at the door of the house, young and old, with blindness so that they could not find the door. [12] The two men said to Lot, “Do you have anyone else here — sons-in-law, sons or daughters, or anyone else in the city who belongs to you? Get them out of here, [13] because we are going to destroy this place. The outcry to the LORD against its people is so great that HE has sent us to DESTROY it.” ... [24] Then the LORD rained down burning sulfur on Sodom and Gomorrah — from the LORD out of the heavens.
Jude 1:7[SIZE=-1] [SIZE=-1]In a similar way, Sodom and Gomorrah and the surrounding towns gave themselves up to [/SIZE][SIZE=-1]sexual immorality and PERVERSION[/SIZE][SIZE=-1].

[SIZE=-1]Romans 1:18, 24-28, 32[SIZE=-1] [SIZE=-1]The [/SIZE][SIZE=-1]WRATH OF GOD[/SIZE][SIZE=-1] is being revealed from heaven against all the godlessness and wickedness of men who suppress the truth by their wickedness.... [24] Therefore God gave them over in the sinful desires of their hearts to [/SIZE][SIZE=-1]sexual impurity for the DEGRADING of their bodies with one another[/SIZE][SIZE=-1]. [25] They exchanged the truth of God for a lie, and worshiped and served created things rather than the Creator — who is forever praised. Amen. [26] Because of this, God gave them over to [/SIZE][SIZE=-1]shameful lusts. Even their women exchanged natural relations for UNNATURAL ones[/SIZE][SIZE=-1]. [27] In the same way the [/SIZE][SIZE=-1]MEN ALSO ABANDONED NATURAL RELATIONS WITH WOMEN AND WERE INFLAMED WITH LUST FOR ONE ANOTHER[/SIZE][SIZE=-1]. [/SIZE][SIZE=-1]Men committed indecent acts with other men[/SIZE][SIZE=-1], and received in themselves the [/SIZE][SIZE=-1]due penalty for their PERVERSION[/SIZE][SIZE=-1]. [28] Furthermore, since they did not think it worthwhile to retain the knowledge of God, he gave them over to a [/SIZE][SIZE=-1]depraved[/SIZE][SIZE=-1] mind, to do what [/SIZE][SIZE=-1]ought not to be done[/SIZE][SIZE=-1].... [32] Although they know God’s righteous decree that those who do such things deserve death, they not only continue to do these very things but [/SIZE][SIZE=-1]also approve of those who practice them[/SIZE][SIZE=-1].
