Religious fundamentalism

Religious fundamentalism is like when someone really, really believes in their religion and they never change the way they believe. It's like when you have a favorite toy and you never ever want to play with anything else, even if someone tells you there are other cool toys out there. Some people who are religious fundamentalists believe that their religion is the only right way to believe and everyone else is wrong. They might do things that seem strange to us, like always praying at certain times of day or only wearing certain clothes. It's important to remember that everyone is different and likes different things, including the ways they express their religion.
