This entire discussion could easily spiral into a cluster%&# of political pissing contests very quickly, so let's all try to be respectful and try our best to actually try to engage with each other as human beings first and tribal rivals a distant second
Any Superman fan with an understanding of the character's earliest history knows that the original Superman as depicted by Seigel & Shuster was very much a political character, who constantly involved himself in hot button issues like unions, spousal abuse, war, racism, housing problems and corruption in both government and business. Had the term been in vogue back then, Seigel & Shuster's Superman would no doubt have been labelled a Social Justice Warrior by conservatives for being an obvious mouthpiece for FDR's New Deal political views.
As the editors at National Comics took more and more control over Superman, the political edginess of the character became more marginalized to the point that Superman's original tagline of being a champion of "Truth and Justice" had "and the American Way" added to remind readers that Superman was now a defender of the status quo, which he remained for most of his existence.
Since then, various creators have dabbled in giving Superman a political edge again, mostly to disastrous effects. Among the most notable were when JMS stupidly had Superman threaten Lois and destroy her evidence of a factory's illegal actions in order to prop up the failing economy of a small town and Goyer's pretentious story in which Superman relinquishes his American citizenship in order to not have his actions be viewed as an extension of American Foreign Policy. While Morrison restored Superman's early scrappy champion of the underdog, the politics were fairly tepid with a few exceptions.
Obviously, Superman is a IP owned by one of the world's largest multinational corporations, which is probably not keen on Superman alienating any of its potential customers by doing anything too overtly political. However, do you think there's room for that SJW aspect of the character to play a role again or has he outgrown that part of who he was? I think the fact that he's an investigative journalist makes him an inherently political character and creators shouldn't shy away from that. The pursuit of truth is a part of who he is.
Again, please be respectful. Thanks.
