The positive power of negative thinking!
Ignoring negative/evil people/things under the pseudo mantra of "being positive" is not only a sign of weakness but it allows negativity/evil to continue and proliferate unimpeded.
It might make you feel better temporarily, ("ignorance IS bliss") but if you refuse to solve your problems, they remain, grow and often return to wreak more havoc. "Thinking positive" was not initially meant to be considered as the opposite sense of negative, but in the sense of affirmation. Meaning, you are positive that you can achieve something; believing that you have the ability. Not that you only focus on the shiny, happy things. In the original sense, "positive thinking" would allow you to believe that you could solve your problem, achieve your goal and this mentality would inspire you to work harder and smarter to that effect. It's like taking morphine for the pain of a bullet wound, it will make you feel better, but it won't heal the damag...
