Okay kiddo, let me explain what the Bodo League Massacre is.
A long, long time ago in a country called Korea, there was a war called the Korean War. During this time, there were many people who supported the North Korean government, and many who supported the South Korean government.
The Bodo League was a group of people who were suspected of being supporters of the North Korean government. Many of them were innocent and had never done anything wrong, but because they were suspected of being supporters, they were put in prison camps.
Later on, the South Korean government decided to try and get rid of anyone who might support the North Korean government, and so they told their soldiers to kill all the prisoners in the camps. This was called the Bodo League Massacre.
It was a very sad and terrible thing to happen. Many innocent people died because they were suspected of being something they weren't. We should always remember this as a lesson to never judge someone without proof and to always treat others with kindness and respect.
