 Colonialism, he says, comes in two flavors. First, the extractive kind. In extractive colonialism, the objective is to extract wealth away. You need a labor class, you need people to work the fields, you need people to work the plantations. You need them subjugated, but you don't need them dead. Then the second, settler colonialism, where the colonizer wants the land without the people. And that, al-Baghdadi says, describes what happened in Palestine.
