You're evidence is from a Star trek series that basically shows "The Eugenics Wars" never happened?There are no words for tonight's episode? Holodecks are not supposed to exist in this timeline
Writers do not give a shit about canon. Canon be damned!

See: ST:YOY - "Future's End I and II" <--- My, pot, meet kettle.
Oh and BTW - go check out the TAS episode: "Practical Joker"
But yeah, there was a production staff that didn't seem to care about canon more than the rest; but it was the staff of a certain Star Trek show that ran from 1995 - 2001 and wrote the Female Captain as if she were Bipolar.
