Sarie:
If you study US history, you'll find that America was founded not on Christian principles, but on Enlightenment principles. Most of the founding fathers -- including Jefferson, the author of the Declaration of Independence, did not consider themselves Christians, but "deists," meaning that while they believed in God, they rejected the divinity of Jesus.
Also, the world has had --and currently has -- many women at the helm of various countries. These include, Germany, UK, Ireland, Israel, Pakistan, India, Chile, Argentina, the Phillipines, Finland, Sweden, etc.
Happy New Year!
