Not sure about Larry and I've got to go with Groucho when it comes to clubs!

Your guess is incorrect. The author's parents where straight he mentioned it in his screed, their son is not straight and statistically their not-straight son is unlikely to produce offspring and the predisposition, which he claims he was born as, to biological disfunctionality will not be inherited by anyone.

With regard to Alan Turing it is hard for anyone to judge what life would be like had he never existed but I suspect our lives today would not be much different. I'm of the mind that in due course someone else equally brilliant would have accomplished what Turning may have. It's pretty clear that his story has some cachet considering the cause celeb that biologically incompatable deviant sexual behavior has been elevated to in popular culture of late. It moved you!
