But specific to modern atheism? No. Modern atheism is a product
  of Christiandom, specifically:
  a) Judaism
  b) Christiandom - East + West met as equals
  c) Roman Church split off from Eastern churches, became Roman
  Catholicism
  d) Protestant Reformation splintered off from Roman Church, to
  "start from scratch", each in their own ways.
  e) The myth of the Reasonable Man came within the tradition of
  the Protestant reformation
  f) The beginnings of modern Science also came from within the
  tradition of the Protestant reformation.
  g) The beginnings of the modern Atheist movement in the 19th
  century also came from that tradition of the Protestant
  reformation. The violent and murderous iconoclasm of the atheism
  within the French Revolution was of a different source.

  Most specifically, the modern atheist tradition pitted itself
  specifically against Southern USA biblical fundamentalism, which
  it seems to fight primarily against to this day.

  In short, the New Atheist movement, line of Dawkins and such,
  has positioned itself primarily against the legalist Bible-only
  mentality of the southern USA Bible belt, a product of a 19th
  century belief in some kind of fundamental divide between
  Science and Religion, a myth that continues to this day.

  In short, if one is an atheist in the 21st century it is a
  product of Christiandom, most directly connected to the
  Protestant reformation movement, hence sharing much of the same
  value system.
