Even though they are the largest sexual minority group in the United States, the lives, joys, and struggles of bi+ people, as well as the social structure of monosexism, are regularly overlooked in social scientific research and broader conversations about sexuality and gender. interrupts this pattern of erasure by providing readers with a sociological examination of sexualities in society that places bi+ people and monosexism at the center of analysis. Through exploring bi+ peoples experiences navigating identity, community, and politics, Lain Mathers argues that to understand and challenge gender and sexual inequalities, we must first recognize and interrogate the structure of monosexism. At a time when attacks on LGBTQ people are increasing, this book offers an incisive examination of how an often-overlooked group within the LGBTQ community makes sense of their place in the world and what we can learn from attending to the specific issues that bi+ people face in society.
