Politicians know this well. Higher echelons of structured religions know this absolutely well. If you instil fear in the minds of a group ( religion, caste, race, nation etc) that others are not good, you gain control over the group.
Carefully analyse all wars, riots, spread of wealth, or inequality in this world, you’d find this equation visible in plain sight. But emotions of fear is more real than analysis of facts. That’s why fake news thrive.
It is a weapon used by a lazy lethargic influencing few to take control of the hard working majority. Why most of the politicians, if not all, in this country are heavily un educated and non-sensical, but come next election, they win ? It’s through careful pollination of fear of other groups.
A Uber driver recently told me he’s Tamil and happily married to a Sinhala lady.
‘How hard is it?’ I asked.
‘No problem sir, We don’t think of it as hard, We don’t think of what others think, but we don’t do any harm either’
Wow. I was stumped.
