It's ironic that the author rejected the parallel of Superman and Jesus on the grounds of that unlike Superman, Jesus and the Bible teach peace and nonviolence. I guess he forgot the numerous times when the God of the Bible ordered the mass slaughter of entire cities. And unlike Superman, God made no effort to spare innocent men, women, children, and animals. Instead, he insisted that they all be killed without mercy (or in some cases, taken as slaves). The author also seemed to have forgotten Jesus' violent rampage through the temple, and his saying he came not to bring peace but a sword. So the parallel may not hold well, but for the opposite reason than the one claimed by the author.
