Black And White
I believe that the internet is black & white. Life, on the other hand, is Technicolor. Big issues are rarely simple. Big questions do not usually come with simple Yes or No answers. That is what makes today's political divide so unproductive and dangerous. Increasingly, people discuss (that is a kind word for it) these thorny issues on social media, and any opposing opinions are deemed wrong, stupid or evil.
On an individual level, we can fall into the trap of believing in a black & white world. Divorcing or divorced spouses often come to believe that the other is always wrong or possesses evil motives. Each one retreats to his or her corner and waits for the bell to signal the start of the next round. This is especially harmful when children are also in the ring.
