The disturbing aspect of atheism is the obvious transfer of moral arbitration to the individual human being. An atheist can rationally claim the right to decide what behaviour is acceptable within the community of human beings as they relate to each other and all other life forms. It is entirely conceivable, and has been proven out in real life, that an entire nation, on the basis of State sponsored atheism, can adopt policies that are considered immoral by the vast majority of the human race. I submit the iron curtain as proof of this. But the reason the vast majority of the human race considered the iron curtain as immoral is that their basis of judging this State behaviour was based on Theism. It is only Theism that keeps the deterioration of atheistic morality in check. Humans are selfish and without a theistic counter to selfishness in the form of altruism, it runs wild when adopted collectively by political parties. In the USA the democratic party has adopted atheism as their foundational philosophy of reality and so can be expected to pursue the examples established by their predecessors in the USSR, Red China, Cuba, Vietnam, Cambodia and East Germany.
The crazy part of this is that in the USA our younger generations have adopted en masse a New Age type of pantheism allowing them to present themselves as spiritual and enlightened but whose core philosophy is identical to atheism as to moral arbitration. They claim to find goodness within. So in other words, like atheists, THEY become the determiner of human moral values. They may parrot Theism with its standard of love and altruism but obviously consider themselves free to practice abortion, sodomy or taking what you've worked to produce to support their pet programs in the name of social justice. I consider these people more dangerous than atheists. Look what they did to Bombay and Calcutta before theists arrived in their land and countered the wretchedness of their society.
