Final answer:
The ethos of the Comic Market Preparations Committee values diversity and minimizes hierarchies by preserving diversity, recognizing the importance of minority perspectives, and acknowledging the power of markets to offer freedom to oppressed groups.
Step-by-step explanation:
The ethos of the Comic Market Preparations Committee in valuing diversity and minimizing hierarchies can be seen in several elements. One element is the preservation of diversity through ghettoization, which allows minority groups to maintain their distinct culture and traditions. Another element is the recognition of the importance of minority voices and perspectives, as seen in the feminist movement's embrace of identity politics and the inclusion of multiple perspectives within the movement. Lastly, the power of markets to offer a degree of freedom to oppressed groups is acknowledged, although market forces alone are unlikely to eliminate discrimination.
