Thought provoking stuff. Her dismissal of real positivity's effects on events is offhand at best, and her willingness to resort to "realism," a bit knee-jerk and naive in its own special way. Her portrait of the dangers and irresponsibility of mandated fake positivity as linked to major international crises, on the other hand, is spot-on. A thought/conflict provoking diatribe, I predict.
It's hard to not be skeptical of her when she starts out with, "Why are all these straw-men so unreasonable?!" I've never heard anyone try to explain effects of positive thinking in terms of magnetic or quantum mechanical forces or whatever. Whenever I've heard about positive thinking it has been on how it affects your own body. Our minds have amazing ways of physically changing our body, and as social creatures our behaviour can affect those around us.
