Hier mal ein paar Beispiele, wo Nietzsche sich irrte, bzw. falsche Schlüsse zog:

Nietzsche:
"In truth,there was only one christian and he died on the cross."

Brother:
Did He? Remember three days after! Now He is waiting at our doors, sometimes knocking shy and silently to remember us to let Him in - to be reborn in us.
-----

Nietzsche:
"Two great European narcotics, alcohol and Christianity."

Brother:
It’s the misuse of both, which makes it narcotic, not the thing itself!
-----

Nietzsche:
"Woman was God’s second mistake. "

Brother:
If there ever have been any mistake at all, it has not been God. A God with mistakes is impossible.
-----
Nietzsche:
"Hope in reality is the worst of all evils because it prolongs the torments of man."

Brother:
Torments do not come out of hope, but out of wrong perception of what is. So, never give up hope! Give up your wrong perceptions.
