Changing Their Tune

The rubes are showing what a bunch of credulous bozos they are.  And having been misled and cajoled and bullied into believing the weirdest bullshit any of these charlatans could dream up for the last 40 years, suddenly Ol' Gran-pappy Robertson wants to pretend he hasn't been punkin' the poor saps all along, and that (contrary to what he's insisted on in the past), the Young Earth thing is "interpretation" and not to be taken literally.  

Fuckin' phony.

So it all goes down The Memory Hole.  They wipe out the version of their own history that's now inconvenient, and they start fresh with, "No, no - I never said that.  Anyone who thought I would say that would have to be a foolish child, and you're not a foolish child are you?"

And so it goes - reset, reboot, repeat as needed.  

As driftglass says, "Always wrong but never in doubt."
