California’s “yes means yes” law turns the idea of sexual consent upside down. Suddenly, nearly all sex is rape, unless no person involved reports it as such.

Consent, under the California law that is spreading to other American universities, is required to be “ongoing throughout a sexual activity and can be revoked at any time.” The law also states that “a lack of protest or resistance does not mean consent, nor does silence mean consent.” Also, previous sexual activity “should never by itself be assumed to be an indicator of consent.”
