Sorry, this sounds like a massive rationalization to not take action. When ETs are brought up these days, people just yawn. The people of this world are far more aware than GE may think. And far more able to cope.
The damage being done to our world by waiting far outweighs the damage by moving forward. The cure for brainwashing? Outing the damned truth.
Is everyone truly that fearful? What a pathetic species we've become.
