The ineffectual complainer is a hateful figure. But much more insidious is the ever-accepting positive person who is a force of inertia in society.
Chances are you know a few: The people who are always trying to get others to look on the bright side; who cannot accept any negativity; who may regard any criticism as unproductive by definition, professing to prefer 'action' (regardless of whether action by itself would actually change anything).
These types are insidious and even downright dangerous because they are disarmingly benign. They are also eminently lovable—certainly to the recipients of criticism, but also because they engender positive emotions in others who are taken in by their attitudes. They negate critique and actively try to get society to ignore ugly truths.
Suppose a man-made disaster happens in a society. These are the people who would advocate not pointing fingers—as was the case in the aftermath of the 2008 financial crisis. They ignore the fact that not laying any blame would likely result in similar disasters happening again in the future, due to the failure to enforce any form of accountability.
Even if these positive people are simply genuinely positive by nature, they must always be treated with a healthy dose of skepticism. It may be difficult—their positive emotions are infectious. But if they are allowed to be dominant, society's progress towards a more positive future would, ironically, be slowed.
