@ slimboyfat...
1914 is too integral a component in their chronology, ideology, and eschatology to be dropped. They simply can’t, it’s a sacred cow... go back far enough and everything hinges on it*.
The overlapping generation thing should be all the proof you need, ‘cause there’s just no fucking way they’d come up with something that weird unless they absolutely had to.
...
*Remember, Fred Franz left no protege, and Ted Jaracz purged out all the creative and outside-the-box thinkers, so there’s no one left with enough narrative creativity to properly overhaul the script... they’re stuck with it.
