Do you know what religion is? It's when people have certain beliefs about things like God or spirits. Sometimes people like to wear special clothes or symbols that remind them of their beliefs, like a cross necklace for Christians or a hijab for Muslims.
In France, there is a law that says schools should be a place where everyone is equal and no one is treated differently because of their religion. This law is called the law on secularity, which means the separation of religion and the government. It's like when you play a game and everyone follows the same rules so that everyone has a fair chance to win.
This law also says that students and teachers should not wear any clothes or symbols that show their religion. This means no hijabs, no crosses, no turbans, or any other religious symbols. The reason for this is so that no one feels like they are being left out or treated differently because of their beliefs.
But some people don't like this law. They think that everyone should be free to express their beliefs in any way they want, including wearing religious symbols. Others worry that if people start wearing religious symbols, it might create divisions between different groups of people.
In the end, it's important to remember that this law is there to make sure that every student feels equal and included in their school.
