The dark side of positive thinking

Every once in a while I see articles like this and I want to reinforce its message that positive thinking is a load of super stinking shit. Not your basic healthy positive thinking but this movement that imagines that by just thinking positive thoughts and imagining positive outcomes things will automatically manifest. From the link:

"What positive thinking actually does is teach you how to hypnotize yourself into ignoring your true feelings. It creates a kind of tunnel vision. You begin to lock your consciousness into a bubble in which you exist only as your 'higher self,' always smiling, full of love and happiness, magnetic and unstoppable. Living inside this bubble might feel good in the short-term, but in time the bubble will burst. That’s because every time you force yourself to be positive, negativity grows within. You can deny or repress the negative thoughts and emotions, but they don’t go away."
