Stands for "disability exclusionary radical
feminist". They're like TERFs except the exclude disabled
people, including disabled women, from the feminist movement and believe disabled
people are a burden and don't deserve right. They also believe that autistic men are trying to rape women because "they are all predatory". They don't seem to acknowledge that autistic or disabled women exist and very ableist, particularly towards people with mental or neurological disorders.
DERF: "Autistic men are all predatory, misogynistic incels who are abusive towards women and want to molest them! Disabled
people aren't even oppressed and mostly choose to be fucking
retarded anyway. What do you mean disabled and autistic women also exist?"
Actual
feminist: "shut the fuck up and stop being ableist, you ignorant DERF".
