Queer erasure

Queer erasure is a heteronormative cultural tendency to remove queer groups intentionally or unintentionally from record, or to dismiss or downplay their significance. Queer erasure (inclusive of lesbian, gay, bisexual, transgender and asexual erasure) can be found in a number of written and oral texts, including popular and scholarly texts. Queer historian Gregory Rosenthal refers to this form of erasure by describing the exclusion of LGBT history from public perception through targeted urban planning and development resulting in the "displacement of queer peoples from public view".
Queer Erasure in Academia and Media.
Historian Gregory Rosenthal refers to queer erasure in describing the exclusion of LGBTQ histories from public history that can occur in urban contexts via gentrification. Cáel Keegan, an Assistant Professor of Women, Gender, and Sexuality studies and Liberal studies, describes the lack of appropriate and realistic representation of queer people, HIV positive people, and queer people of color as being a type of aesthetic gentrification, where space is being appropriated from queer people’s communities where queer people are not given any cultural representation.
Erasure of queer people has taken place in medical research and schools as well, such as in the case of AIDS research that does not include lesbian populations. Medicine and academia can be places where visibility is produced or erased, such as the exclusion of queer women in HIV discourses and studies or the lack of attention to queer identities in dealing with anti-bullying discourse in schools.
Straightwashing.
Straightwashing is a form of queer erasure that refers to the portrayal of LGBT people, fictional characters, or historical figures as heterosexual. It is most prominently seen in works of fiction, whereby characters who were originally portrayed as or intended to be homosexual, bisexual, or asexual are misrepresented as heterosexual.
Bisexual Erasure.
Bisexual erasure refers to attempts to ignore or reexplain evidence of bisexuality, and may include the belief that bisexuality does not exist, or is simply a phase. Bisexual erasure often causes struggles for bisexuals even from within LGBT communities. 
Lesbian Erasure.
Lesbian erasure is the tendency to ignore, remove, falsify, or reexplain evidence of lesbian women or relationships in history, academia, the news media, and other primary sources. Lesbians may also be ignored within the LGBT community and their identity may not be acknowledged.
