According to Taiaiake Alfred and Jeff Corntassel's Reflection article "Being Indigenous: Resurgences against Contemporary Colonialism," how is postmodern colonialism different from earlier colonialism?

Alfred and Corntassel write about contemporary colonial practices and it's various forms through time.

The idea of the colonial system, in general, is gaining control over a group of people and their land, but in the contemporary frame and postmodern colonial system, it has been much more subtilized.

Earlier forms of colonialism are remembered in history by aggressive militaristic attacks, forcible missionaries and educations, removal of children, land confiscation and various other forms of compulsive, sometimes violent, forms of domination.

Recent years have shown rise of the subtle, but persistent Imperialistic practices of postmodern colonialism.

This means that Indigenous peoples have been removed from state's frameworks, while being under the pressure of the general political, legal and cultural norms that do not suit them, and which do not apply for them, their life, tradition, and learnings. With this, the right of self-determination is hurt, as well as their citizenship standards.
