I'm not sure about that (the icon bit). I've gay friends who have been surprised that Turing was gay - personally I knew about it since I knew about Turing, but I was a nerd who was interested in the theory of computation. It's only relative recently (with the popularity of unbelievably lousy character-assassination like "the Imitation Game"*) that he's been more in the general public eye, I think.

• This is a shit film that represents the worse of pandering, and casts Turing in an appallingly poor light, whilst leaning into the "autistic savant" trope hard. It's abysmal.
