The closeminded people with certainty in their hearts see the actions which they cannot understand, the actions which are something other than the idiotic and acceptable conformities of our corporate owned society, and they label them insane.
Anything that dares to question the mindless conformity, anything that goes against the corporate social norms, is simply dismissed out of hand as the reasoning of an unbalanced mind.
And everyone's social norms are the corporate social norms, whether or not you even watch TV, as the vast majority of people are watching, and we all are having to deal with such people and we all are having to make sure to appear 'normal' and thus we all are following the corporate social norms. The ultimate goal of which is to not think too hard, don't really question what is going on around you. Just go buy more stuff.
Van Gogh was a stalker. He sent a woman he loved a 'present'. Such was utterly beyond the understanding of our norms. He was said to be bipolar, schizophrenic, even perhaps to have had an ear disorder. The reality is simply that he was an artist who dealt in terms of symbols and who had fallen in love with someone that was utterly indifferent to him in return. He wanted to express to her how badly she was hurting him with her indifference. He did so quite grandly. Of course, not understandable to the average person, and simply dismissed as insane. And also can be dismissed as an evil stalker who should be locked up of course.
