What the person puts forward is logical, it is sometimes expressed as the window “Overton Window”. They push too far so that they can compromise on what was once a “hill to die for” becomes compromise. Like Russia v Ukraine. Since Ukraine won’t give up the land Russia originally wanted back in its control, Russia takes much more, then the idea that they get the “Donetsk” is papatable. The further the insanity is pushed, the more “normalcy” or the status quo loses.
