But why move the Eugenics Wars? They are perfectly fine in the 1990s, where they were explicitly said to take place. Sure, Roddenberry and Company didn't set out to make an Alternate History, but that doesn't mean that Trek can't become one. There is nothing about Trek that precludes it not being our future. I've heard this argument before that if Trek doesn't represent our actual future than all the "meaning" is lost, which is a load of garbage.
"Canon is only important to certain people because they have to cling to their knowledge of the minutiae. Open your mind! Be a Star Trek fan and open your mind and say, 'Where does Star Trek want to take me now'." - Leonard Nimoy
