Wendy McElroy recently wrote an excellent summary of the methodological and philosophical problems with the commonly repeated claim that 1 in 4 college women have been the victims of rape and/or attempted rape.
Most disturbing is what McElroy calls the “re-definition of sexual violence” to count as rape sexual activity that doesn’t involve even threats, much less violence.
