I noticed that too, but who cares? Evidently homosexuality was acceptable among Greeks. I suppose the situation was similar to that in say Afghanistan today, men and women segregated and men resorting to the practice as a pressure valve and social ladder-- to establish hierarchy. It doesn't seem unreasonable to suppose Alexander participated in the practice.
He was a murderous bastard, a proto-hitler. I don't care if he screwed knot-holes in fence posts, frankly. I see nothing to celebrate in the life of this tyrant or any reason to worry about his reputation.
Part of the facts that made alexanders conquests of note was that he did not impose culture on the conquered and often adopted local practices. It was the first efforts of various cultures co-existing (in a bloody savage world).
He also established the library of Alexandria. When commerical ships came to port, they would be inspected for scrolls to be taken and copied. If it was a document of value the owners would be given the copy.
Homosexuality was never accepted by the Ancient Greeks. Even the homoadvocates support the notion that homosexuals did not exist then in any more than they exist now. Homosexuals were segregated appart from normal society. I do simplify because the real issue here is whether Oliver Stone takes liberties which the actual historical evidence does not support.
Not the first time for stone, History channel right now is doing a conspiracy piece about the Kennedy assisination which discredits Stone's "JFK" as absurd.
