(CNN) "The wait is over," proclaims the copy on Showtime TV's website. The cable channel is heavily promoting Saturday night's boxing match in Las Vegas between Floyd Mayweather Jr. and Manny Pacquiao. The cable network is going all-out to raise interest to a fever pitch for what it is billing as "one of the most anticipated fights in boxing history."

There is something missing here: Amid all this hoopla, as corporations and promoters line up for their big pay-per-view payday, there is a resounding silence on Mayweather's documented history of domestic violence -- no mention of any accountability or responsibility.

That Mayweather is a serial batterer of women cannot be disputed. According to the sports website Deadspin, Mayweather has had at least seven assaults against five women that resulted in arrest or citations in addition to other episodes in which the police were called but no charges filed.

Some examples: In 2001, he allegedly struck the mother of one of his children in the face with a car door and then punched her several times in the face. According to an account in the Las Vegas Review-Journal : "Mayweather was charged with two counts of domestic battery. He pleaded guilty in March 2002 to those counts and one count of misdemeanor battery in an unrelated case.

"Under the plea agreement with prosecutors, the boxer got a suspended six-month jail sentence, a $3,000 fine, 48 hours of community service and two days of house arrest."

Questioned by CNN reporter Rachel Nichols last year about his abusive behavior, Mayweather showed little remorse. He noted that there were "no pictures ... just hearsay and allegations." He has previously said he should not be compared to O.J. Simpson or Chris Brown because there are no pictures of the women he has allegedly abused -- as if the lack of video or photographic evidence is equal to exoneration. In fact, Mayweather spent several months in jail in 2012 after pleading guilty to misdemeanor assault charges.

What is astonishing here, however, is that the public is willing to overlook Mayweather's misogynistic, violent behavior outside the ring. Consider how well all the hype over the Mayweather-Pacquiao fight is paying off. The Los Angeles Times reports that gambling on the fight is expected to be heavy, with one MGM Resorts official estimating the total amount of wagers at $80 million. The 16,800-capacity MGM Grand Garden Arena has sold out, generating a record $74 million.

Such collective indifference by the public of Mayweather's domestic abuse is curious considering other incidents involving football players. After video surfaced of Ray Rice punching his then-fiancée (now wife) in an Atlantic City, New Jersey, elevator, he was temporarily suspended by the NFL and later dropped by the Baltimore Ravens.

Adrian Peterson was likewise suspended by the Minnesota Vikings for harshly disciplining his son. These punishments occurred amid widespread outrage among fans and the public over what was deemed unacceptable behavior by athletes. Such outrage seems to be absent when it comes to Mayweather.

Mayweather's history of abuse can be seen as even worse when we remember that he is a professional fighter. He makes millions throwing punches. He earns his living using his fists. The fact that he uses these same fists to beat women does not seem to matter to CBS (which owns Showtime), the MGM Grand, the Las Vegas gaming industry or the sponsors associated with Saturday's fight. If any of them has made a public statement about his domestic abuse, I have not been able to find it anywhere online.

At its best, a boxing match can be thrilling, artistic and mesmerizing. Unfortunately Mayweather's longstanding domestic abuse issues tarnish both the sport and the fans that choose not to hold him accountable for his behavior.
