Racism and the role of women in Shakespeare's society are central to the understanding of the play but it can't be interpreted through their lenses or the entire meaning disappears into political grievance. The play is about jealousy. The difficulty a lot of the Po-Mo's have with this is that to them racial or feminist politics cannot be considered contributory to this theme but definitive. And they aren't.
There is, as well, a difficulty with the fact that Shakespeare provided this window to the human soul several hundred years before the tenets of feminist and postmodern literary criticism pretended to discover the means of accessing it. And worse, he appears to have been a white male himself and hence incapable of appreciating it. My guess is that they'd just as soon forget Shakespeare altogether and they just might do that. I think he's too big to twist.
Bloom was held in great disdain when I was at the University of Houston.
But then, the freaks I went to school with thought Derrida, Foucault, and Irigaray were the last word in lit crit.
