Controversial: This is an exclusionist group, and is not valid within the LGBTA+ community
A Pan exclusionist or BAB (Battleaxe Bisexual) is someone who believes that pansexuality, omnisexuality, polysexuality and other m-spec labels other than bisexual contribute to biphobia and transphobia. typically these people send death threats, doxx and harass people who are or support m-spec labels, despite them saying they are merely "defending" bisexuality. BABs are similar to TERFs in the sense that they think theyre defending and helping their cause (bisexuality for BABs, feminism for TERFs) but are doing nothing but harm. BABs also could be considered REGs, due to Exlcusionist mostly being used for those who think asexual/aromantic are not LGBT. the original term for BABs was an inclusionist made term, however current BABs twisted the term into an exclusionist term instead. not all pan exclusionists are BABs, however most of them are.
