In case you are still following this I figured I would briefly share this. Note I am not a Christian but rather a bit of a neopagan and polytheist.

One of the huge problems of course is how Christians relate to the story of the Fall from Eden. You hear this brought up all the time, and the lesson they draw from it is follow social mores. Don't rock the boat, don't rebel. But a close, careful reading suggests:

1) The fall from Eden is foreshadowed in Genesis 2 with the description of marriage.

2) The forbidden fruit is general heterosexual activity. This is particularly obvious when including a look at Middle Eastern iconography and, in particular, figures like the Pazuzu, who had a serpent-headed penis. Yes, the tree of knowledge is knowledge in the biblical sense ;-).

3) This act of rebellion creates the Biblical model of (heterosexual) marriage.

The problem for Christians is that the very model they want to push arises from the very act of rebellion they want to use to bludgeon everyone else into submission.

I have heard that argument but nobody has shown me evidence that the Ken doll was advertised as gay, which is what's important really for this target market.
