Imperialistic Gender Binary Gender

Man and woman are the two genders that western culture upholds. It would be difficult to define it any other way with history portraying just man and woman. The concept of binary gender has been ingrained into the western society, this is no question. No where is is taught that non-binary genders are recognized within this country. To imply the concept of the gender binary as the most valid form of understanding gender is to also state that the imperialistic gender construct is the only perspective a culture should use to define gender. By definition this would state that the presence of non-binary genders that do not fit into the category of man or woman would not exist and in turn any culture that would have these notions of a non-binary gender spectrum would be invalid as a culture.
