Okay kiddo, so there's a thing called anarchism which is basically the idea that people should be able to live their lives without someone else telling them what to do. It's like when mom asks you to clean your room and you're like, "I don't want to, I want to play!" but with grown-ups and important things like work and government.
So, some anarchists believe that there should be different kinds of anarchism. They don't want to all follow the same set of rules because then that would be like having a leader again. Instead, they want to have different kinds of ideas about how to live without rulers, but still work together.
It's like if you and your friends all wanted to play a game, but you couldn't agree on which game to play. So instead of arguing and not playing, you decide to play a bunch of different games at the same time in the same room. You're all still playing, but you're doing it in your own way.
That's what anarchism without adjectives means - it's a way for people to be anarchists but also have their own specific ideas about how to do that. They don't want to be labeled as one type of anarchist or another, they just want to do what feels right for them. It's like when you don't want to be called a boy or a girl, you just want to be you!
