civil rights legislation was backed by the national guard. Mandaterd busing actually moved people from one place to another. Equal rights resulted in people actually working at certain occupations, attending certain schools and patronizing certain establishments. That happened because people violating the law could be prosecuted for doing so. It represented a sea change in our nation's culture. Rape has been a serious crime for a long time. There has never been any doubt about the abhorrent nature of the act.
In the end, if a woman says, "he raped me", even if he did, nobody will be able to do anything without evidence. You can't lock people up without proof. A law mandating certain negotiations without any way to prove that those negotiations actually took place will be a toothless exercise in futility. And the politicians who put it in place will lose credibility and possibility elections because of it.
