"Does'nt it seem just everybody shouts at each other nowadays?
I think its because conflict is drama. Drama is entertaining and entertainment is marketable!
Finding consensus and common ground is dull. Nobody wants to watch a civilized discussion that acknowledges ambiguity and complexity. We want to see fireworks!
We want the sense of solidarity and identity that comes from having out interests narrowed and exploited by like-minded zealots! Talk show hosts. Political candidates, news programs .All become successful by reducing debates to the level of shouted rage.
