Albanian nationalism in North Macedonia means that some Albanians who live in North Macedonia believe that they should have more rights and recognition as a group within the country. They feel proud to be Albanian and want to protect their cultural and linguistic heritage, which is different from the majority of the people who live in North Macedonia.
Imagine you have a group of friends who all like different things. Some of them love playing soccer, some love playing video games, and others love playing music. Each one of your friends is different, but you still all like to hang out with each other. However, sometimes your soccer-playing friends might feel like they don't get enough recognition for their skills or that other friends get more attention. They might start to feel like it's not fair, and they want everyone to know how much they love soccer.
It's kind of like that with Albanian nationalism in North Macedonia. Albanian people want to make sure that their culture and language is recognized and respected even though it may be different from the majority culture in the country. They want to be able to speak their language, have access to education and jobs, and feel like they belong in their own country. It's important to remember that everyone deserves to feel proud of who they are and where they come from, and Albanian people in North Macedonia are no different.
