Today’s piece of argumentation comes from Slate, where James Sturm is making the case that moviegoers who care about comics should eschew The Avengers this summer. His reasoning: because Marvel Comics has treated Jack Kirby, a longtime creator for Marvel who helped the company prosper, like dirt.

What makes this situation especially hard to stomach is that Marvel’s media empire was built on the backs of characters whose defining trait as superheroes is the willingness to fight for what is right. It takes a lot of corporate moxie to put Thor and Captain America on the big screen and have them battle for honor and justice when behind the scenes the parent company acts like a cold-blooded supervillain. As Stan Lee famously wrote, “With great power comes great responsibility.”
