Gynocentrism is the practice of placing women's safety, comfort and general well-being at the center of social or political concern, and structuring life in the objective service of such interests. It extends no further than that, and would NOT include placing the feminine point of view at the center of one's worldview. That is to say, gynocentrism does not violate the boundary of inner space by requiring a person (male in particular) to think and feel a certain way. In sum, gynocentrism is not totalitarian.
Gynonormativism goes the extra step. Using gynocentrism as a foundation, gynonormativism prioritizes the feminine point of view hierarchically within the culture, on both a political and interpersonal level, and pressures males in particular to adopt a feminine system of values as a component of one's authentic personality. In this manner, gynonormativism is totalitarian. We would understand feminism as a gynonormative project, while acknowledging that it could not have come into operation without a preexisting base of gynocentricity in the traditional culture.
Gynonormativization is integral to the establishment of female supremacy.
