Isn't it better to let off steam? Prevents an explosion.

"If you are active online, you will, at some time or other, have been drawn into an argument you found yourself simply incapable of winning," wrote R Matthan. "Every time we get into an argument online, the facts we present in support of our position seem, paradoxically, to strengthen the hands of our opponents. They frustratingly cherry-pick those parts of our statements that suit them best and use it to their advantage, in the process turning our own arguments against us without appreciating the merits of our propositions taken as a whole." This is the "backfire" effect and leads to fake news aimed at "carefully selected cross-section of people" who already believe in what they are being told. Research by psychologists shows that these are narcissistic people who like to belong to a group to make up for their perceived lack of power, wrote M Hogenboom. This whole discussion about fake news has blown up since Donald Trump was elected president. Main stream media has relentlessly discredited Donald Trump's victory, blaming it on Russian interference, while Trump has labeled them as bearers of fake news. This only polarises people into those who voted for Trump and those who voted against him. Most research blames social media as an 'echo chamber' where like minded people exchange false  information in complete faith. They believe that media companies must have automatic fact-check and delete anything that is not true. Which means they will control what news we get. Trump and Modi win because their supporters believe what they say without checking for truth, wrote A Varma. Till a couple of decades ago there was a broad consensus on truth. "There were gatekeepers to information and knowledge." True, but until recently white people actually believed that blacks are inferior because it was 'scientifically proven'. Mainstream media would have supported that view. Today, it would be completely unacceptable to say that there is any difference between black and white. Only someone who is black can write that a successful black nation does not exist because of "chaos, senseless wars, corrupted religiosity, violence, and economic collapse" and black activists are also responsible, blaming racism for lack of progress of blacks. But whites are no different. Poor whites in southern US vote for whites even though it is against their own interests. The European Union is an example of how the elite have become separated from the people, leading to a vote for Brexit, wrote Prof D Rodrik. This is why liberal democracy is under threat. Maybe liberal democracy was myth propagated by a controlled media. Today everyone can have a say, even if based on false beliefs. Maybe that is the way to prevent world wars.
