Men are just predisposed to predatory behavior.
No, we're not. As noted above the actual frequency of such abuses is tiny when weighed against the size of the population, and women can be just as predatory. A deciding factor is undoubtedly physical size, which skews the numbers in terms of who might actually succeed in victimizing someone else.
Societally, we've definitely sexuality as conquest for men in general and from puberty (or even before) its basically viewed as a race amongst boys to lose their virginity.
That's broadly true but not really problematic, as it is also reflective of differences in physiology and hormonal influences. Due to the nature of sexual reproduction it is women who suffer the consequences of sexual coupling (i.e. pregnancy), and young men feel quite natural compunctions to sow their oats, so to speak. This difference in outcome is quite drastic, and is ultimately the root of all our gender roles.
There's a tendency among some people to believe that gender, and therefore roles or attitudes associated with gender are nothing more than social constructs. However they frequently forget that gender is derived from sex, and human beings exhibit a fairly notable amount of sexual dimorphism (i.e. physical differences between the sexes). Men truly are, in general, bigger and stronger, women are generally more skilled at multitasking and social interaction, and when a man and a woman have sex, it is the female who is saddled with a 9-month long physical condition that grows steadily more incapacitating as it builds towards labor.
As a result, it's not exactly a surprise that rape is so terrifying and traumatic to women. Not only is it a loss of their agency, but also a loss of control over their own fertility. In today's world we have widespread contraception, and many of us are supportive of abortion, so victims of this crime might not suffer the full extent that pre-modern women would have, but we are an evolved animal and the echoes of this primal fear are still present within the psyche.
It's not 'patriarchy' which drives this. It's not a mass conspiracy of misogyny which produces different attitudes regarding male and female promiscuity, and in fact is is that women consider THEIR sexual potential to be so precious that the prevalent behaviors we see have developed. Simply put, because both men and women see female sexuality as something to be earned by men, men will continue to chase women and, generally, not the other way around. Men will still be seen in the eyes of many as being successful if they manage to persuade many women to sleep with them, and women will be viewed by many as devalued if they are easily persuaded to give away their 'precious' attribute. It's not born of misogynistic imposition, but instead the patterns of behavior baked into our brains via evolution. That's not to say it is necessary to preserve or anything, but despite decades of feminist pressure to try and reform society to their liking, the patterns persist and even find greatest expression in the most egalitarian societies.
It's really time to stop saying that men are the problem, or are predisposed to predatory behavior. Harvey Weinstein was an incredibly powerful tycoon protected by a corrupt, sick industry. He's not reflective of the 98% of men who never commit sexual assault or rape, and neither is Gylfi Siggurdson if it emerges he is guilty. They are reflective of rich, famous or powerful people who are not used to facing accountability.
We really gotta kick all these shitty notions that still pervade our society.
I agree, and one of the most important ones to get rid of is that boys are slime and snails and puppy dogs tails.
