Like the article said, he is seeing everything biblically through a serpent seed lens. That is the reason I saw no point in debating the issue with him in the first place. My reason for posting is to bring it to the attention of others who wouldn't know one way or another.
You pointed out the scriptures that sing out to him his theory. I think with the 2 Cor. he was just being sarcastic with you. You and I will never see it that way.
All women should be insulted by his comment to 1 timothy. My sex are considered too stupid to be trusted. You being a man like adam, are suppose to have more sense. So you are considered the bigger liar if you don't see his version of truth. Women are too stupid to be complete liars.
Be careful trying to understand him better, it may make you feel a little crazy.
