@Lionnir,
Remember, I'm the one who said I don't think there was much in the bible that is relevant to the 21st century. The bible is mostly stories of war, rape, incest, murder, misunderstandings and people brutalizing other people. Not that those things don't happen today, it's just there doesn't seem to be any significant connection. However, you might want to talk about why some people have such hatred towards homosexuality and then find the references in the bible that they use to make their case. There is that wacky church that protests at military funerals because they claim God is punishing the US for allowing homosexuals to have rights. They claim the "word of God" is what drives them to this action and they believe that God's word is the bible. Many Christians claim to follow the teaching of Jesus, who loved and accepted everyone, but then use Old Testament references to do just the opposite.
Some people also use the story of Jacob and Esau to justify the conflict of Israel and Palestine. It's historically incorrect to do so, but that has never stopped a fanatic from doing it.
