Hi. A lot of your objections are just odd, I'm sorry. What is "immoral behavior"??-- that phrase is not found in the Bible. The context of 1 Cor 5:1-13 is idolatry. Paul objects to Christians going to temples to other gods.

The quote from Genesis 2:24 is clearly to Jesus as a divine bridegroom, as Paul clarifies in Eph 5:23. You're not following the Divine Marriage references very well, I'm afraid. But you didn't come to me for instruction. You came to insult and bloviate.

I've dealt with both polygamy (clearly encouraged throughout the Bible), and Romans 1, which is clearly not about two people of the same gender touching each other. Stop hating people.
