Why "not all men" is not a valid argument : 

Because some 16% of women will be forcibly raped at some point during their lifetime, and too many men are indifferent or in denial of the facts.  The number I stated above comes out of statistics kept by RAINN https://www.rainn.org/about-rainn  indicate that over their lifetime, one in six (16%) of women will experience an attempted or successful forcible rape.
The FBI uniform crime report says that  some 67345 women were raped in 2012, while only some 12100 men. for those who can't count well, that's some 5.5 women raped for every 1 man.
Consider also that not as many people report being raped out of shame, fear or embarrassment, and you'll see that we have a real problem here. 
There are all too many sexual predators out there, and the overwhelming percentage of them are men.
