M-Spec Exclusionist

  An M-Spec Exclusionist, also known as a Battleaxe Bisexual (BaB) or Band-Aid Bisexual (BanBi), is an exclusionist who believes that pansexuality, omnisexuality, polysexuality and other m-spec labels other than bisexual contribute to biphobia and transphobia. They also believe that m-spec labels are the same as bisexual.

History and Explanation
The term Battleaxe Bisexual was coined by an unknown person, and they themselves were pro-pansexual, however, the term was reclaimed by exclusionists and is now an exclusionist term.
