As I slowly became aware of politics, I admired Thatcher, like many others did, as a "strong leader." It was only after I discovered I was gay and studied politics that I realized her policies were, in fact, anti-gay.
Progressives will likely take umbrage with the movie's glorification of Thatcher. But in the end, Thatcher's obstinacy becomes her downfall. No matter how the movie glorifies her rise to power, her fate is the strongest indictment of her character.
