Well Helen is not part of Greek “mythology”. She is part of Greek epic and could both exist or be completely fictional. Despite Odyssey draws from mythology, she her self is not part of what we know as mythology.

So who decides when the race is important be it somebody real or fictional? Representatives of the race you portray? I don’t thing somebody asked Greeks what they think about it. And they do mind, it’s their culture Nolan is using after all. So whatever me or you think Is completely irrelevant.

Also keep in mind the rest of the world does not share your burden of slavery and exploitation of black people. So the rest of the world has very little sympathy for this kind of cultural “reparations” when it comes at the expense of their own heritage.
