So, I decided to do some digging and found an article that set the record straight (no pun intended)
Here's a snippet:
I wanted to know if there was any gay sex/love in the film? “No”, he replied abruptly, his tone changing… as if this question had been asked too many times, or… this was a question that he had been expecting, but didn’t want to answer. Realizing there was something amiss, I asked Graham if he was gay. Graham told me that he is a straight man. I told him rather grandly that all of my films had gay themes. Perhaps, sensing my ire, my gay militancy or simply knowing that a gay film maker in Hollywood is perceived as a lesser film maker, to some… no more than a pornographer, Moore boasted that he had gone to great lengths to purge the film of anything gay. He didn’t want Turing’s gayness to be a ‘distraction’. He didn’t want gay sex to ‘put off the majority’. He was adamant that he didn’t want his film to be a gay film.Now I have a clip of Graham saying it himself
I warned him that his rather old fashioned attitude could cause a backlash… that Turing was an important part of our LGBT history. That Alan Turing had been tortured by the state for being gay. Moore scoffed that I was still in a minority and people were interested in Turing the man and not Turing the gay man.
