I've read the letter "ATAR KFIRA OR ATAR HOFESH?" and your response,
and a few things sound very wrong:
You say you have a right to state your views in a "complex issue like God",
And you definitely do.

But in the HOFESH site itself you regard this "complex issue" with extreme
simplicity: You claim that idea of God is sheer nonesense, and back it up with
a mateuristic philosophy.

First of all, this is hypocritical: If you view the concept of God as nonsense,
how can you look this man in the eye and say "we have the right to say our
word in this complex issue...". For you it is not a complex issue.

Secondly, it damages your cause. Here is why: Most of the attacks in your site
are 100% right: Dilugei Otiot, Gimatria, the cheap demagogy of the
religious preachers, the power of Shas, etc.

For the jewish theist, unraveling the current ugly face of Orthodox Jaudism
is hard enough to swallow. Throwing in the "fact" that God is a
nonsensical concept, makes your mission a total impossibility.

This is not just "being nice in order to avoid hurting the theist's feelings".
It is being fair. "Dilugei Otiot is a Religious Merchants Demagogy" is a
provable fact. "God does not exist" is an opinion. If you are not careful to
differentiate the two, most people will regard everything you say as mere
"opinions", which we both know is not true.

Of-course, the God that the Haredim believe in is self-contradictory.
Saying that this kind of God is nonsense is indeed a fact provable by logic.
But the God of Spinoza, or Descartes, or even the Rambam, is a deep
concept one cannot prove or disprove. Such ideas of God are also far from
meaningless: They are complex philosophical point of views. Atheism is
just as profound and complex: Saying that the atheist knows God doesn't
exist just like "he knows that a polar bear isn't drinking orange juice behind
his back" just shows your incompetence in philosophy. The real points in favour
of atheism are much much more complex.
