Atheism is to believe in the void.
The only true atheists I've seen are when I turn on the evening news and see rapists and murderers. Rapists and murderers hide their tracks so they won't get caught by society. But they don't believe there's an invisible cosmic force seeing what they do in private. Neither do they believe there's any recompense, neither now nor later. Atheism is nihilism.
It is rare to find true atheists, although they are a growing percentage. Atheism eventually leads to mental illness, antisocial behavior and at some point a life of in-the-moment carpe diem, the ultimate expression being selfish criminal activity. And at advanced stages, assault, rape, murder and drug addiction.
It is only when one begins to look at cosmic order and harmony and that the possibility of a Creator exists who will one day bring about justice on our lives here(and after here), that mental healing can occur. And with it, social order and community.
Socially, communism is a perfect example of this breakdown. Stalin's Russia led to state sponsored atheism which bled down to the people, destroying their will, incentive and drive. Even after the fall of the USSR in 1991, the rot of atheism had devolved into oligarchies of former KGB factions, criminal activity and former government thugocracies. The people simply did not have enough God belief culturally to allow them to be honest enough to confront their problems.
Atheism is for losers. Atheism eventually kills and destroys. Ironically, islam is very similar to atheism in that it believes in power only(through submission) and pursuing it in this life via the rise of the Caliphate. Islam believes in State power, which is why the left has joined forces with it. State power, coercion, totalitarianism whether through 'allah' or 'Obama', 'Stalin' or whoever, makes no difference. Faith is not required. Only force.
Thus atheism will always devolve into he who rules by might wins. Take what you want. 'Do what thou wilt' is the whole of the law. Whether by the sword of allah or the kalishnikov of Russia or the vote of one John Roberts upholding the bureaucracy, it is all force against the people that matters against the darkness of the night of the void, the State must come in to bring its imprimatur and assign it as law against heavenly, unseen law. The individual be damned.
I'd probably only vote for an atheist in name only. A real one like Obama or Khalid Sheikh Mohammad or Stalin or Charles Manson would eventually be too much to bear just like body odor is too much to inhale when an armpit is pressed into one's face all day, the smothering of the nanny state and its demands.
