1. An evil act of desecration and contempt for the woman involved and, by extension, all women.
2. Just like rape, it is an act which is primarily motivated by hostility towards women and the need to control women and it becomes a way to compensate for the viewer or the perpetrator's underlying feelings of inadequacy and feeds his issues of mastery, control, strength, authority and capability (e.g., David Lisak & Susan Roth 1998).
3. Men who enjoy watching or performing "bukakke" are diagnosed with paraphilia ("sexual deviancy" in scientific terms) according to the Diagnostic and Statistical Manual of Mental Disorders by the American Psychiatric Association as paraphilia is the "recurrent, intense sexually arousing fantasies, sexual urges, or behaviors generally involving... the suffering or humiliation of one's partner" (DSM-IV, 2000).
I certainly wouldn’t want to be judgemental about the lifestyle or recreational activities of the men who have posted on this subject thus far, but as a clinical psychologist I can only advise them to seek psychiatric help as soon as possible because paraphilia is more than a personality quirk.
Moreover, there are some people from the FCC and the FBI have an invested interest in paraphilics as one form of sexual deviancy tends to lead to another and several studies confirm that men who enjoy watching "bukakke" have an elevated risk of engaging in sexually coercive behavior.
