The FBI has a glossary of terms it associates with extremist, involuntary celibate individuals (incels) and members of religiously or ethnically motivated violent extremism (RMVE), including popular internet slang such as “based” and “redpilled.”
The conservative Heritage Foundation’s Oversight Project recently obtained copies of FBI training materials relating to involuntary celibate violent extremists (IVEs) and RMVEs. Among the documents the conservative think tank received was a glossary of terms the FBI lists as indicators of IVE and RMVE affiliations.
