I agree that government & religion should be kept separate. Just as government and morality, government and charity, government and sex, government and family values, government and love, government and hate, government and compassion should be separate.
The government's role should be to serve the citizens by providing defense of our borders, providing a framework for interstate commerce, protecting public health & safety and punishing those who are preyed on by manipulative evildoers.
We should not abdicate our humanity or our responsibility to our fellow man to the government.
