When Friedrich Nietzsche wrote the often quoted phrase in his book “The Gay Science” in 1882, he was not saying that the Christian God had died. He wrote the phrase to illustrate that Enlightenment had eliminated the possibility of the existence of God.
But many have knowingly misinterpreted the statement to use Nietzsche’s phrase to bolster their own specious arguments. You know, the same people that think it’s a good idea to wear a tin foil hat, overturn an election and follow the Kardashians.
