Hey there kiddo! Pashtunization is a big word that refers to the process of making people become like Pashtuns, who are a group of people from Afghanistan and Pakistan.
You see, Pashtuns have their own language, traditions, and culture that they follow. And sometimes, they want other people to follow those things too. So, when Pashtuns try to make other people become more like them, that's pashtunization.
For example, let's say you have a friend who is not a Pashtun, but they start learning Pashto, the language that Pashtuns speak. They may also start wearing traditional Pashtun clothing, eating Pashtun food, and celebrating Pashtun holidays. This is what pashtunization is all about - spreading Pashtun culture to other people!
However, it's important to remember that not everyone wants to be pashtunized. Some people like their own language, culture, and traditions, and that's perfectly okay too! It's all about respecting people's choices and differences.
