Outrage
Among the basics of microeconomics is an idea called supply. Demand and supply when acting together can balance each other to decide the price or consensus over value for any commodity. I think that social outrage in the past few decades has become a commodity and hence can, to some extent, be subject to supply-demand considerations.
When there is more supply than demand for anything, the price (read as - value) of that thing falls. Currently, there is more social outrage over anything and everything than we can handle. So, we get habituated to it making the demand fall. This depreciates the value of social outrage, which can be catastrophic for our collective future. Lesser value of social outrage can translate to its lesser impact on any real social change. We are risking losing the vitality of a limb of our democratic setups called the expression of dissent, just so we can feel good about ourselves in those few minutes when we are too bored to focus on our lives.
Among many other reasons, one reason for more than demanded supply is the ease of outrage made possible by social media. In the Indian Independence struggle, to demonstrate your outrage against the colonial tyrant, you had to lift your ass, go to the street, participate actively with your head and limbs, get beaten up, and come back bruised to a poverty-stricken house without much food. The outrage was costly and hence maybe more valuable and valued. Today, to demonstrate and get appreciated for your outrage you have to click and share things on your phone while you are in bed. If you feel too enthusiastic about the cause you might press your fingers on the keypad for a few more minutes to add a caption to the outrage-filled share. Social media has made social outrage cheap; it's almost free if you aren't too sensitive or sensible of a human being.
So, if you think that you are helping the present society by diffusing social outrage through twenty daily posts in hyper-connected social media networks, you should be the one to take the blame for raising the threshold of inelasticity for the future. However well-intentioned you might be, you will still be responsible when after a few years no one would give a fuck about the things that were once worth having an outrage for. Cheap outrage will make people numb. The ease of outrage will destroy its value and corrupt its purpose.
