Google's current #1 definition of rape, when searched ("definition of rape"), is:
"The crime, committed by a man, of forcing another person to have sexual intercourse with him, esp. by the threat or use of violence."
A later definition on the same page states:
"The abduction of a woman, esp. for the purpose of having sexual intercourse with her."
Acts of sexual assault, including rape, can be committed by any person. It is definitions like this that perpetuate the widespread fear of men among women (and "prison rape" jokes that insinuate a man raping another man). The F.B.I., which recently changed its definition of rape to be more inclusive, estimates that 3% of men will be raped as an adult. Additionally, 40% of these men identify as heterosexual. And because of the vast underreporting of male sexual assault, especially when they are assaulted by a woman, this number could be much higher.
Rape is about establishing power and control, characteristics that can be exhibited by all people. In fact, women who exhibit a form of implied dominance over their partners, such as having a better paying job, are more likely to assault them regardless of their gender.
Google needs to realize that, when it comes to rape, men are not the only assailants and women are not the only victims. A popular search engine providing erroneous information about something so serious could end up being extremely harmful.
