Okay kiddo, let me explain protests against the war in Afghanistan to you. You know how sometimes people disagree about things and they use their voices to express how they feel? Well, that's kind of what's happening with the war in Afghanistan.
Some people believe that the war is not a good idea and they think that it's causing more problems than it's solving. They may think that it's not fair for people to be fighting and losing their lives because of a war that they disagree with.
So, to show their disagreement, these people come together in groups called protests. They hold up signs or chant things to make sure their message is heard loud and clear. They want the people in charge to know how they feel and maybe even change their mind about the war.
Protests are a way to peacefully show that you disagree with something and want it to change. People have the right to express their thoughts and feelings, and that's what these protesters are doing. Does that make sense, kiddo?
