Some do.
Atheism IS a philosophy and a belief, because either one questions or one does not question.
That's a unique and, frankly, incorrect definition for "philosophy."
God may not be seen, but his effects may be very much visible. Slavery is inherently vested in the ability of certain natural or human wielded forces to leverage against our physical needs and other material powers.
Wow. Can you say that in English?
YET! there are countless documented cases of people who are not wielded by such forces, there are countless cases of emancipation that do not ultimately depend on those forces, and there are also supernatural accounts of God emancipating people.
Okay, I get it. But the personal experiences of someone who feels free of materialism and the limits of their own desires hardly constitutes any kind of proof.
Anecdotes are not documented cases.
Why does atheism ignores the case of emancipation of man from nature???? While it is such a self evident FACT!!!
A personal anecdote is hardly a self-evident fact.
Most atheists choose atheism because they are skeptics to begin with, and one person's account is sufficient to lead one to begin to believe in the supernatural.
Unless atheism is another ideology for evil people that negates emancipation, inducing people to submit to their will and power, as those who can manipulate the atom would then have the ability to black mail all.
Versus those who can manipulate church teachings and religious beliefs?
THere is a difference between a nation under God, and Bin Laden cloaking himself with God while enslaving himself to secular means of violence. The nation under God implies a balance of powers competing to serve us, while Bin Laden's Jihad is a religious cloak over very secular beliefs.
The cloth does not make the monk indeed.
