CW/TW: The following article contains exclusionism towards m-spec identities other than bi. If this topic upsets you, please exit this page.
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 all m-spec labels are the same as bisexual.
BaBs are against the usage of the "multisexual" label in of itself. This is because they believe that bisexuality is the only 'true' label, thus making the term m-spec 'redundant'.
Bloodshed Bisexual is a term used by Battle Axe Bisexuals who believe doxing, threats, cyberbullying, suicide baiting and more are okay. Many Bloodshed Bisexuals also like to call themselves Battleaxe Bis, but you can usually tell by their content and reputation which one they are.
