A Longsword Lesbian (LSL) is a term for exclusionary lesbians fighting against what they believe is "lesbian erasure"; they feel that the label "lesbian" has been watered down too much by the existence of non-binary, pronoun non-conforming, and multisexual-spectrum lesbians. Longsword Lesbians may also use the terms Vixenamoric and Sapphomoric to be more discrete about their exclusion.
Longsword Lesbians exclude PNC lesbians in the belief that pronouns equal gender, and that the term "lesbian" is only applicable to she/her binary women who are attracted to other she/her binary women. While this is already reductive considering the rich history of gender nonconformity and experimentation in the lesbian community, there are also many languages that lack gender-specific pronouns.
The vincian counterpart is Gravity Knife Gay.
Identities Excluded
This is by no means an exhaustive list; Longsword Lesbians exclude anyone and everyone who is not strictly a binary, she/her woman.
