That didn't stop a LOT of fans - in this thread, too* - (and even some professional writers - see the recent rather tedious romulan war books) from trying. And largely failing to come up with a satisfactory explanation.
*Which is entirely appropriate, considering the thread title, despite your opinion, King Daniel Into Darkness
. BTW, haven't you been trying to reconcile various contradictions from trek canon in this very forum?
PS - I do agree that, if and when the discussions degenerate into ~'it rapes my childhood' statements (it's been known to happen) - well, their only remaining value is their unintentional hilarity.
