How to resolve racially stressful situations  (transcript)
Summary
There is a scary story about a tsunami in Japan. It's not that a tsunami is dangerous but humans’ action is dangerous.
About 100 years ago, a very big tsunami came to a small village. Many people were killed. The rest of people built a stone monument as a sign that ahead of here was dangerous to live because of a tsunami. People started to live above there and to train running away from tsunami while remembering the big tsunami and looking at the sign.

However, as the months move on, people forget them. They started live in cities which were built over reclaimed shorelines which were ahead of the sign, around it, many buildings were built, they didn't become realizing it, they forgot it, and again a tsunami came there. Of course, many people died. Mothers must teach their children that tsunami is dangerous and Children must learn it, but they are caught by a tsunami.

The speaker used the word tsunami in the TED talk.
Still, there is a racial problem in our current world that black people are not treated as human but they who are adults and children also are killed suddenly when they see others. They can't call police because police also kills them. The accident occurs like a tsunami. It's too sudden to run away.

Teaching, learning, and making rules can't stop its accidents. Black people are placed in the stressful situations always, but it's created by humans. It's not a natural disaster like a tsunami.
Humans must have a love at least for their children. People Just imagine their own when they see black people. The only solution is this and revenge is not a solution.
