One small point, if I may. Nietzsche's father died when Nietzsche was five years old. Although he certainly cast a large shadow over the female dominated household during the boy's formative years, and although his legacy certainly was a strong influence on Nietzsche choice to pursue theological studies for a time, I think it's an overstatement to assign Nietzsche's eventual animus to religion to his father's "overbearing" presence in his son's life.
Nietzsche came to his theological views honestly, I would say, through intellectual conviction, taking into account, of course, the important role the passions played in forming the life-governing myths under which he chose to live.
