Clearly one cannot mock that which does not exist, therefore the atheist that denies the existence of "god" does so with the intention of making a truthful statement, and not with the hypocritical intention of mockery. The author seems confused about what words mean and how they should be applied. Possibly the intent is deliberate and the author is mocking those that dare disagree with him by refusing to partake of his mythology?
You're right when you say, "not with the hypocritical intention of mockery", since being hypocritical actually engenders some departure from a belief in, or adherence to some standard.
In fact, one who might conventially be called a hypocrite usually doesn't really believe in anything...except the adrenaline rush perhaps, that might issue from cavalierly branding someone else's heartfelt beliefs "mythology".
Even more clear is the fact that atheists can not know whether God or a Creator, whichevr you prefer, exists. Therefore, the atheist does not make a truthful statement when he denies the existence of God, he instead offers a hubris filled opinion. Which is fine, we're all entilted to an opinion.
But my question here is, do you have a problem with private organizations excluding atheists?
Probably the author knows his own opinion and the opinion of most of his readers.
Those of us who know G-d understand that the fact of G-d's existence is obvious to all. We also recognize that some want to deny G-d's existence because they understand what it would mean to accept someone greater than they could ever be. Human pride stands in the way.
But you are correct that G-d is not mocked when you deny his existence.
You do, however, name yourself a fool.
Clearly one can mock that which exists that one does not believe exists.
One of the greatest unbelievers of them all, Bertrand Russell, admitted that rigorous logic would not permit him to deny God's existence as a proveable fact. Agnosticism was as far as careful thought would permit him to go.
At any rate, the Boy Scouts is founded on an implicit belief in God. To contend one should be allowed to participate while expressly rejecting the existence of God is PC illogic taken to extremes.
