Political radicalism is a big word that means someone who wants to make really big changes in how things work in their government or society. Imagine you've been living in a house with your family and sometimes you feel like things aren't fair or you want to change some rules. Maybe you want to stay up later or have dessert before dinner. A political radical is someone who wants to change big things like how the government is run or how people are treated.
Sometimes, political radicals believe that the government has been unfair for a long time, and they want to change things in a big way. They might want to get rid of certain rules or laws that they think are hurting people or making things worse. They might want to create new laws or systems that are more fair or helpful to everyone.
Political radicalism can be really exciting for people who are passionate about making a difference. But it can also be risky, because some people might not like the changes that are suggested. Political radicals have to be careful not to be too extreme or upset people too much, because that can backfire and make it more difficult to achieve their goals.
Overall, political radicalism is about wanting to bring big changes to society or government, and it's important for people to be thoughtful and respectful when engaging in this kind of activism.
