What is the main conflict in This Bridge Called My Back: Writings by Radical Women of Color by Cherrie Moraga?

"This Bridge Called My Back" is a compilation of poetry and prose writings from feminists from cultures considered in the late-1970s to be Third World. That category included virtually every skin color except white, and dramatically changed the experiences for those American women. Several of them were also identified as lesbians meaning their oppression was two-pronged, frequently coming from inside their culture just as sharply as it came from outside it.
