Okay kiddo, let’s talk about anti-liberalism: Anti-liberalism is when some people don't like the ideas that come with being a liberal. Now, being a "liberal" means different things in different places, but basically it means believing in liberty and equality for all people. This is important because it means that everybody has a chance to have the same opportunities and to make choices for themselves.
But some people don't like this idea. They might argue that some people are better than others, that some people deserve more than others, or that everyone should follow the same rules even if it's hurting some people more than others. These people might say that the government should have more control over people to keep things "in order." This kind of thinking is anti-liberalism.
So, anti-liberalism is when some people don't like the idea of everyone being equal and having the same rights. They prefer to have things unequal and to have the government make more decisions for people.
