Atheism is not a rage against any god. It's simply a denial that one exists. C.S. Lewis
is hardly quotable, here.

A-theism rejects all theology. A theology may mean a specific religion or it can mean a
belief in metaphysical or occult systems of belief. It can also mean a political dogma such as found in Stalinism.

It does not mean however a rejection of the beauty of life or living things. It doesn't require a shallowness or lack of depth as some have stated. It can be a capacity for reverence
for the natural world and artistic appreciation as well. It can include compassion for people and animals and a social concern for the well-being of the world and its inhabitants.

The true test of an atheist is to redefine the definitions and criticize the frames offered
by religionists as definitions of atheism.
