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 support, inclusion, and visibility in both bisexual and non-bisexual communities, especially in the LGBT community.
