Complete victory of New Atheism would be a calamity, and the nature of the question suggests the (a)theocratic false ambitions of the New Atheists, who have been hyped into thinking atheism some kind of scientific proof to it.
Assets/Christianity and Liabilities/Atheism
In Atheistic Society the liabilities/evil are the norm, with there being a rejection of elimination/execution by society. Atheistic societies are considered by Progressives/Liberals to be the pinnacle of being humane. The problem with Atheism is the evil/liabilities leads to disease, death, destruction and poverty that requires massive health care/welfare/entitlement programs to sustain Atheism. Since the Atheists have no assets, they must steal (redistribute wealth) from the Christians for the survival of the Atheists. Atheists reject God because they think they can do a better job of setting up a set of rules for society.
And a little Christmas
Atheists Celebrating Christmas: Worse Than Christians Believing Jesus Was Born on December 25th?
Richard Dawkins sings Christmas carols and celebrates Christmas itself, which he says is a religious festival people of religion- and no religion, can share. That's very kind-hearted of him, but why is Christmas an exception when other Christian holidays such as Good Friday are ignored by atheists? If you want to argue that Christmas was founded on paganism thus making it a faux-Christian holiday and acceptable to atheism, where is the logic in practicing paganism which is as illogical to them as believing in God? It's clear that receiving presents and singing simple melodies takes precedence over logic.
