Certainly bad things still happen, and we are, indeed, living with the negative effects from teachings and beliefs of the past. We ARE, however, improving our society and opening ourselves to new ideas and ways of thinking.
Nature steadily moves life forward, eyes forward, never looking back.
Nature has never read the Bible, and doesn't know all these important values God supposedly wants us to follow. Life just continues to go forward, no matter how hard the conservatives want to return it to the morality of the 1950's. You would think that their time and energy would be so much more useful embracing the future rather than fighting to reverse it. But they cannot seem to grasp that very simple and very obvious fact of life. They insist that their time was a better time and want every child in America to experience the childhood that they did - whether they want to or not.
