Today, 23 June 2012, is the one hundredth anniversary of the birth of Alan Turing. As indicated in the film, when Turing was 41 years old he either was murdered or committed suicide after having gone through chemical castration for the crime of being a homosexual.
To say that Turing was a genius is perhaps an understatement. When one thinks of modern computers, particularly of artificial intelligence, one might be thinking of what we call a Turing machine. His one contemporary who had equivalent mathematical insights into machine "thinking" was Alonzo Church (warning, this gets into some very complex mathematical theory). These geniuses were linked by their theories which came together in the Church-Turing thesis.

To be fair, one is probably no more likely to be a genius if one is gay or lesbian than if one is straight. Most LGBTQ people I know are not of genius caliber. Most are just ordinary people Ordinary people who long to be first class citizens. Not special other than how every human being is special. Wishing to not be placed on a lower tier of a caste system.
