This chapter focuses on individual and cultural invisibility through an exploration of how bisexual, pansexual, asexual, and plurisexual identities are invisible within three specific contexts –– education, the workplace, and the mainstream mass media –– and on how if these identities are made visible they are often invalidated or erased. Some researchers and organisations have conducted school climate studies with students who are lesbian, gay, bisexual, pansexual, or asexual, or who identify with plurisexualities. It is possible that those with bisexual (and pansexual, asexual, and plurisexual) identities, like lesbian and gay people, are open to bullying and harassment. Bisexual (and pansexual, asexual, and plurisexual) identities may also be invisible or invalidated in higher education, including on university campuses, and in curriculum and course content.
