What is "bisexual erasure"

n. A tendency to ignore or deny the existence of bisexuality.

Bisexual erasure or bisexual invisibility is the tendency to ignore, remove, falsify, or reexplain evidence of bisexuality in history, academia, news media and other primary sources. In its most extreme form, bisexual erasure can include denying that bisexuality exists. It is often a manifestation of biphobia, although it does not necessarily involve overt antagonism.

There is increasing inclusion and visibility of bisexuals, particularly in the LGBT community. American psychologist Beth Firestone writes that since she wrote her first book on bisexuality, in 1996, "bisexuality has gained visibility, although progress is uneven and awareness of bisexuality is still minimal or absent in many of the more remote regions of our country and internationally."
