Ira Glass recently admitted that he is not all that into Shakespeare, explaining that Shakespeare's plays are "not relatable [and are] unemotional." This caused a certain amount of incredulity and horror—but The Washington Post’s Alyssa Rosenberg took the opportunity to point out that Shakespeare reverence can be deadening. "It does greater honor to Shakespeare to recognize that he was a man rather than a god. We keep him [Shakespeare] alive best by debating his work and the work that others do with it rather than by locking him away to dusty, honored and ultimately doomed posterity," she argued.
Rosenberg has a point. A Shakespeare who is never questioned is a Shakespeare who's irrelevant. And there are a lot of things to question in Shakespeare for a modern audience. One of those things, often overlooked in popular discussions of his work, is his politics.
Shakespeare was a conservative, in the sense that he supported early modern England's status quo and established hierarchy, which meant defending the Crown's view of divine monarchical right and opposing the radicals, often Puritan, who questioned it.
For all the complexity and nuance of Shakespeare's plays, his political allegiances were clear. James I was his patron, and Macbeth in particular is thought to be a tribute to the King. It even includes a reference to the Gunpowder Plot assassination attempt at James. That reference is made by Lady Macbeth as part of her effort to convince her husband to murder Duncan. The villainous traitors in the play are thus directly linked to traitors against James.
