If the apparent connection between Turing's conviction and sentencing for being a homosexual, is real, and he killed himself as a result of that, it is undoubtedly a tragic event.
I suppose there could be a biological connection between sexuality and artistic or scienitfic creativity, but it seems to me that there is a social connection between the two. A person who feels themselves separate from the main group, has greater potential for seeing things in in a different light.
