Constructive, Vindictive Or Destructive

I am all for constructive analysis and commentary. An open progressive society should always have that. However, is our society somehow more like the cartoon below ... always finding something negative to say, ... never considering the backdrop or context. It is easy to just criticise and complain, somehow by shading something darker, it makes our pitiful life bearable. In much the same way, we run the danger of branding ourselves by what we do not like, we have no problem telling others what we don't like. How do people describe you? Is it "oh, she doesn't like lamb dishes, she cannot stand Sungai Wang complex, she hates Justin Beiber,  ...." or is it "she loves dogs, she goes gaga for Baskin Robbins, she loves to climb hills ..."
