Institutional liberalism is the idea that our government and laws should protect individual rights and freedoms, promote equality, and provide opportunities for people to improve their lives.
You know how when you're playing a game with your friends, there are rules to make sure everyone is playing fair and everyone has fun? It's kind of like that but with our whole community and country.
In a liberal society, everyone has the same rights and nobody is considered more important or special than anyone else. It means that people can speak their minds, practice their religion or beliefs, and love whoever they want without being punished or discriminated against.
Institutional liberalism also means that the government sets up institutions, like schools and hospitals, to help people improve their lives and have a fair chance at success. It's like if your parents wanted to make sure everyone in your class had a good snack for recess, so they set up a snack table with enough food for everyone.
Overall, institutional liberalism means that our laws and government are set up to protect everyone's rights, promote fairness and equality, and help people have a good life.
