The gaping hole in those who make 'moral' claims.

Nietzsche's moral philosophy is primarily critical in orientation: he attacks morality both for its commitment to untenable descriptive (metaphysical and empirical) claims about human agency, as well as for the deleterious impact of its distinctive norms and values

hiding behind a cloud, 

Your 'immoral' accusation is made as if  'morality' was normative and static as opposed 

to morality varying from time to time under whims and sentiment of human kind.  Morality

is not a constant like the metaphysical clouds you hide out in its shape undergo constant
