a) This is sexist. Newer research is coming out all the time that's including phrases like 'forced to envelop' in order to capture men coerced into sex that have been habitually excluded by existing statistical measurement, and when those options come into play, men and women nearly equally report sexual victimization. Even now, though, organizations like the CDC capture those new categories in separate areas of their reporting, and to date refuse to put their findings in with sexual assault, so the male numbers are kind of hidden.

As an example, here's the APA:

b) The trend lines for sexual assault in Canada are either declining (UCR police stats) or flat (GSS public surveys). The rate is NOT increasing.

c) Several studies into sexual perpetrators shows that HUGE (60-70%) proportions of them were victimized themselves, typically by female caregivers, as children. They don't just come out of nowhere.
