POST COLONIAL THEORY

I'm learning about an academic and activist phenomenon called Post Colonial Theory. I never heard of it before, and I might be severely misconstruing what I've learned, but it seems to me that the bedrock of Post Colonial Theory is as follows:

Heterosexual white males of European descent began to overrun the world not long after Columbus sailed, and eventually wound up carving out a world-wide colonial empire which marginalized and exploited the people of the Americas, Africa, and Asia. This marginalization and exploitation continued for centuries, until it began to fall apart after World War II. 

Even now though, heterosexual white males of European descent continue to marginalize people of other races by insisting that the best way to gain knowledge is through the use of the scientific method, observation, experiment, logic, and reason, supported by rigorous, peer-reviewed research. These methods are products of Western culture and are used as tools of White Supremacy to keep people from previously colonized ethnicities on the margins of society.

The solution is to reject these Western white male "hetero-normative" tools of White Supremacy and use other traditional, emotional, non-rational methods of gaining knowledge. This is the kind of thinking behind the website A Pathway to Equitable Math Instruction (endorsed by the Oregon Department of Education), which states that that “white supremacy culture shows up in math classrooms” when educators require students to show their work. I wish I'd known that when my high school algebra teacher insisted that I show my work. I could have confronted him about how unfair he was being.

What the Post Colonial Theorists seem to want to do is to jettison white male heterosexual educators who use the tools of White Supremacy like the scientific method and logic, and replace them with educators who are not white, male, or heterosexual, and who do not use White Supremacy tools like logic and reason.

This all seems to be based on a value judgment that white males of European descent are evil because of this history of imperialism. If that is true, then the vast majority of the people claimed to have been marginalized by white male Europeans are also evil. On every continent with the possible exceptions of Australia and Antarctica, ethnic groups have engaged in imperialism, conquering and subjugating people of other races, exploiting them, and remaking the conquered lands into their own image.

It began with Sargon of Akkad and continued through the Babylonians, Assyrians, Chaldeans, Persians, Egyptians, Chinese, Mongols, Arabs, Turks, Zulus, and Maoris, to name a few nonwhite ethnicities who have embarked on a program of conquest and subjugation.
