Your views are totally a-ok with me!
I'm just glad to strike up a conversation with a fellow Superman fan.
The analogy between Christ and Superman have been drawn for decades now and as an atheist coming from a Hindu background I can safely say that it's not just the Abrahamic religions. The striking analogy is there in the story of Krishna (an incarnation of Shiva, born as a human, adopted and raised by a farming couple, grows up to be cattle herder all the while hiding his extraodinary abilites whilst saving lives and coming into conflict with a meglomanical king who ruled the lands). You can look it up in the Bhagavad Gita (a Hindu text)
May I ask you something? You said that Jor-El sent his son to Earth purely to escape imminent destruction. I agree that a father's instinct would be to save their child from an impending doom and I do believe that is one of the reasons, but do you believe it to be the sole reason? Have you ever wondered why Krypton failed as a world? For a world of nations that was several hundreds of thousands of years ahead of us in evolution and scientific understanding, you would think they would be able to save themselves as a society from an ecological disaster even if the planet itself was doomed? Have you ever thought about the political or social structure on Krypton and considered that they suffered from the same societal flaws that we have today in our world?
Perhaps I've thought a little too hard into Superman stories
. I think religious (but certainly not evangelical) and political themes in Superman make for thought provoking stories. For example, I was always fascinated by Lex Luthor as a young boy and as I grew older I came realise that his characterisation, abilities and beliefs are not that far off from real people in our world, both past and present.
