Radical feminism questions why women must adopt certain roles based on their biology, just as it questions why men adopt certain other roles based on theirs. The reason is that the societal forces it deals with seem so great in magnitude that they make it impossible to identify any innate masculine or feminine attributes except those which are results of the biological attributes. Women who organize women-only events are often unfairly dubbed separatist.
Separatists are sometimes literal, sometimes figurative.
