Alright kiddo, so "liberalism" is a big word that means a bunch of different things depending on where you are and who you ask. In Austria, it basically means a few things:
First, it means that people should be free to make their own choices without the government telling them what to do too much. For example, if you want to start a business, you should be able to do that without having to get a bunch of special permits or pay a ton of taxes.
Second, it means that everyone should be treated equally, no matter where they come from or who they are. This is called "equality."
Third, it means that the government should help people who need it, like if they don't have enough money to live on their own or if they're sick and need help paying for medicine. This is called "social welfare."
Lots of people in Austria believe in these things, and they belong to a political party called the "Liberal Forum." They want to make sure that Austria is a place where people are free to make their own choices, but also where everyone gets the help they need to be happy and healthy.
Does that make sense, sweetie?
