There's atheism and then there's Atheism.
Mere atheism is simply disbelief in the divine and as such is not a holy cause to which all other actions are subordinated, nor is it a affirmative virtue which cancels out all other personal faults. Whereas Atheism with the big "A" takes what is otherwise a simple philosophical position and blows it up into an illusion of positive virtue.
Atheism with a big "A" allows dull and ordinary people to feel and pose as if they were somehow superior to the mass of humanity. Atheism with a big "A" also provides reactionary garbage such as the Marxists a means to pose as some kind of progressive vanguard when in fact they are simply putting a philosophical polish on the neolithic practice of beating up and killing people and taking their stuff.
As a mere atheist all I have to say to the big "A" professional Athiests is, "go home, grow up, and get a life!"
