I would agree with this in theory but in practice it makes no sense. The free thinkers here just have a lot of patience and time on their hands. Also the movement has woken up more people than if well enough was left alone.
You would literally have to round up over half the US population now. That half of the population has also been stock piling guns and ammo. That half also likely consists of the people that would be needed to round up everyone of the free thinkers. Leaving the round up impossible to accomplish.
A better explanation is that this is a great awakening.
