The solution

 I recently read a book called 'Bel canto' by Ann Patchet about few terrorists and their capturees locked in for two months. They almost forget their roles and befriend others. More importantly, the captured people understand the terrorists and commiserate with them and so do the terrorists.

There is a also an article in  The Atlantic about a Ukaranian family and 5 Russian soldiers stuck in a cellar. Hiding from further shell attacks. Russians told their side of the story - a propaganda fed to them by Kremlin. But realized that their information is so very wrong. Russians are not liberating Ukaranians but destroying their lives. And the Ukaranian family realized that more than patriotism or support for Putin, Russian soldiers are in this war for the money. 

Politicians in any side of conflict feed plenty of propaganda to people. And people fall for it. Little realizing that what they are doing is not some kind of holy war, but simple plain war - nowhere near holy. 

So I got my Eureka - which is shallow like  my Eureka moments. Lock up some RW people and others like RG supporters/ leftists in a room for a week. This may certainly help them to understand others' viewpoints. But we are doing the exact opposite with social media - feeding the viewpoints, articles and videos which support their political viewpoint - strengthening their belief and increasing their intolerance towards the other side.
