Another reason people do not like radical feminism is because they may think radical feminists are "man-haters". This is because of an author named Valerie Solanas. In 1967 Valerie Solanas wrote the SCUM Manifesto. SCUM was Society for Cutting Up Men. She wrote in it that women should get rid of the male sex. Solanas tried to kill Andy Warhol. She also shot Mario Amaya.
