The way the author ties in positive thinking brainwashing to political apathy in the last chapter was very well done too and I couldn't agree more with her conclusions. As someone involved in trying to fire people up to participate in activism I absolutely find the 'nicey nicey at all costs' mindlessly positive attitude to be an enormous obstacle in effecting real positive change. Just enormous. 

Expressing legitimate anger is helpful and necessary. If you do this it passes quickly! Far better to vent for a little while to friends who understand than to repress all your feelings and so end up feeling unhappy far longer, in the end.
