Bisexual erasureBisexual erasure (or bi erasure), also called bisexual invisibility, is the tendency to ignore, remove, falsify, or re-explain evidence of bisexuality in history, academia, the news media, and other primary sources. In its most extreme form, bisexual erasure can include the belief that bisexuality itself does not exist. Bisexual erasure may include the assertion all bisexual individuals are in a phase and will soon "choose a side", either heterosexual or homosexual.
