It doesn’t matter what this book has written in it for anyone that is outside of your religion. Especially when it comes to writing laws in any country. You can’t expect for people to adhere to or support a law that is written based upon a book that a lot of people think is a large collection of do good stories and fits of rage by an overbearing god. Why would we not use the Koran or the book of mormon or Wiccan texts to write laws? Because they aren’t accepted by everyone who would be governed by such laws. You have every right to follow the religion of your choice. Just as I have every right to not follow your religion.
