Well it’s not like they go around advertising that they are harassers and rapists.
The statement also assumes the numbers are equal, but predominant amount of assaults are perpetrated by a minority of people. So you have a small number of abusers who victimize a large amount of people.
I think you are missing my point here. “No man seems to know” is precisely because because it’s hidden. It’s not that they don’t know, it’s that they don’t know that they know, because people don’t advertise their acts.
As for statistics, general crime statistics in everyday category point to a minority of people perpetrating them, unless you are saying that this is somehow different from all other behavior.
Thanks for the patronizing instead of “educating”. I’m sure your that will help to actually address the problem.
