File this under: Better Late Than Never. *SPOILER ALERT*
So, about a month ago, when issue #900 of Action Comics was released, there was a short story in there called, "The Incident," (written by David Goyer), in which Superman renounces his American citizenship. Well, this created a big uproar among conservitives and right-wingers who were disgusted with the idea of Superman giving up, "Truth, Justice and the American Way." (By the way, he does this because he wants to show solidarity with other people around the world and doesnt want his actions to be seen by other people as U.S. intervention)
First, something to say about why this makes sense: Superman was raised in the U.S., but he wasn't even born on this planet! So, of course, it would be realistic for him to renounce any kind of allegiance to any one country, (or planet for that matter). Superman, as a hero, is interested in saving people, no matter their race, ethnicity, color, religion, sexual orientation, or species!
Secondly, at a time when there is so much scapegoating and hatred directed towards immigrants--or just anyone who "doesn't look American"--it is refreshing for someone like Superman to take a stand like this and say, "Fuck your papers."
