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.
Macbeth isn't a one-off to flatter the King, either: Rebels and usurpers in Shakespeare's plays are always the bad guys. When Hamlet spits out the lines:
Oh fie, fie, 'tis an unweeded Garden
That grows to Seed: Things rank, and gross in Nature
Possess it merely.
The vision of sickening wrongness there is in part repulsion at his mother marrying his uncle, but it's also a political disgust at the fact that the rightful ruler is gone, replaced by a usurpur. What’s "rank and gross" is not just sexual impropriety, but perversion of divine order. The Tempest is about restoring the rightful Duke to his place in spite of his usurping brother, while Othello shows that Shakespeare's sympathies are not just with kings, but with any authority figure, as the sneaking underling Iago attempts to overthrow his noble Captain. It is significant here, too, that (as many critics have pointed out) Iago has no real motive for his animosity. He does not articulate a critique, or even a complaint, about the way Othello exercises power. Instead, he simply says:
I hate the Moor
And it is thought abroad, that ‘twixt my sheets
He has done my office: I know not if’t be true;
But I, for mere suspicion in that kind,
Will do as if for surety.
Rebellion against one's superiors is presented as a matter of misguided jealousy and intrinsic spite. Similarly, the Puritan Malvolio in Twelfth Night, who aspires to the hand of a woman above him in social standing, is a hypocrite and a fool. The Puritan political resistance, or the Puritan ideological opposition to hierarchical norms, is never voiced, much less endorsed.
