Separation of church and state works better than any theocratic government. It is the responsibility of the people to learn to discern and pass ideas of responsibility to their children. Only lazy people who refuse to take responsibility for their own actions (or lack of training their children) would scapegoat a free secular society where everyone can learn to live together and savor the diversity of such a culture.
“Men [and women] never do evil so completely and cheerfully as when they do it from religious conviction.” — Blaise Pascal.
“Teach your children well.” — Crosby, Stills, Nash & Young. But recognize that human beings are not perfect.
