WHY would there be disagreement over what his religion is? Remember the days when being a fanboy brought people together?
There were still arguments. I remember vividly the Marvel vs Dc discussions when I was in school.....*sigh* 22 years ago. "Marvel is more realistic and gritty" "Dc has better characters" etc etc. The difference was all we really had were the comics with Superman and Batman being the only A list heroes with films. So, DC fans were united together and so were Marvel fans (and those of us in the middle that liked both). But now with multiple films, shows, comic reboots, animated features.....fans are no longer united. Think of Man of Steel..it almost literally split the Superman fan base in half.
