Okay kiddo, this is a tough one. Genocidal rape is when people are being raped in a big group because they are from a different place or race. This is done on purpose to hurt or kill them, not because the people who are doing it want to have fun. It's like when someone really bullies another person, but it's much more serious and violent.
When a group of people wants to kill or hurt another group of people, sometimes they will use rape as a weapon. They do this to create fear and make people flee their homes. It's terrible and mean because rape hurts people, physically and emotionally, and can lead to lifelong problems.
It's important to remember that this kind of behavior is never okay, and it is something we must stand up against. We need to work together to make the world a safe and kind place for everyone, no matter where they come from.
