The problem with Greene isn't her position, it's how she got there. "Jewish space lasers" and "staged school shootings" aren't reasonable opinions reasonably reached, and if she suddenly changes those opinions from one day to the next, the only reason would be the realization that they may not be politically expedient. Her position wouldn't actually change, and her methodology for arriving at one would still be the same- the only difference is that she would have learned to conceal the nuttiness for the sake of convenience.
And, BTW, Lindsey- if Greene says "yeah, those videos were manipulated," and you simply buy that for the sake of your party's convenience, then you're being manipulated; and you're buying for your party the methodology that is the problem to begin with.
