The main cause of sexual violence is domination and power over others. Curra mentions the elements of manipulation, power, control, anger, and sadism fused together in a vicious sexual act (p. 210). Men have always been the stronger ones in the relationship and sexual inequalities create power differentials where "rape can be used as a form of social control turning women into helpless victims, without the ability to stop what is being done to them." and can be a way to prevent them.” punishing those who are perceived as deviating from important gender norms (p. 216) and “women being the property of men, women living virtuous lives, and women being devalued have contributed to the occurrence of sexual violence” (223). Sexual violence is used as a measure to ensure the domination of power over other men and women (p. 217). In times of war, it called for desperate measures and rape was used as a defense mechanism to demoralize and humiliate the opposing force (pp. 217-219). Additionally, rape was used as a biological weapon (p. 221) to ultimately eliminate the opponent because the women on the opposite side carried the other side's babies, which would eventually purify everyone so that they either on the same side. Sexual violence may also be rooted in social and cultural factors (p. 223) in which certain cultures view and contribute to the equality of all genders (i.e. men, women, gays, lesbian, transgender, heterosexual, bisexual and pansexual) (p. 223). .227). On a social level, many influencing factors add to the causes of sexual violence. For example, fraternities create an aggressive environment between pride-seeking males (p. 225). Another social factor has been modern technology which allows the abuser easier access to his victim.
