Others, namely Ms. Richards and Ms. Mueller, are less-famous starlets or former “nobodies” whose relationships with Mr. Sheen have been disparaged as purely sexual and transactional. The women reside on a continuum in which injuries are assumed and insults are expected.

“Gold diggers,” “prostitutes” and “sluts” are just some of the epithets lobbed at the women Mr. Sheen has chosen to spend his time with. Andy Cohen, a senior executive at Bravo and a TV star in his own right, referred to the actor’s current companions, Natalie Kenly and Bree Olson, as “whores” on MSNBC’s “Morning Joe” program on Tuesday. Arianna Huffington sarcastically tweeted that Mr. Sheen’s girlfriends “symbolize modesty, loyalty and good taste.” Mr. Sheen’s own nickname for Ms. Kenly and Ms. Olson  “the goddesses”  is in its own way indicative of their perceived interchangeability and disposability.

It’s these sorts of explicit and implicit value judgments that underscore our contempt for women who are assumed to be trading on their sexuality. A woman’s active embrace of the fame monster or participation in the sex industry, we seem to say, means that she compromises her right not to be assaulted, let alone humiliated, insulted or degraded; it’s part of the deal. The promise of a modern Cinderella ending  attention, fame, the love and savings account of a rich man  is always the assumed goal.

Objectification and abuse, it follows, is not only an accepted occupational hazard for certain women, but something that men like Mr. Sheen have earned the right to indulge in. (Mr. Sheen reportedly once said that he didn’t pay prostitutes for the sex; he paid them “to leave.”) One can’t help but think that his handlers might have moved more quickly to rein in their prized sitcom stallion if his victims’ motivations weren’t assumed to be purely mercenary. (Or if they enjoyed parity and respect with regards to their age, influence and earning power.)

These assumptions  about women, about powerful men, about bad behavior  have roots that go way back but find endorsement in today’s unscripted TV culture. Indeed, it’s difficult for many to discern any difference between Mr. Sheen’s real-life, round-the-clock, recorded outbursts and the sexist narratives devised by reality television producers, in which women are routinely portrayed as backstabbing floozies, and dreadful behavior by males is explained away as a side effect of unbridled passion or too much pilsner.

As Jennifer Pozner points out in her recent book “Reality Bites Back: The Troubling Truth About Guilty-Pleasure TV,” misogyny is embedded within the DNA of the reality genre. One of the very first millennial shows, in fact, “Who Wants to Marry a Multimillionaire,” was notable in that it auctioned off what producers called the “biggest prize of all”: a supposedly wealthy B-movie writer named Rick Rockwell  who was later revealed to have had a restraining order filed against him by a woman he’d threatened to kill. According to Ms. Pozner, the reaction of one of the producers of “Multimillionaire” was, “Great! More publicity!”
