Actually I didn't think people did think that or were saying that, wolfperson (sorry you're name is too long for me to cope with)
My gut response to that, was simply that the characteristics she described were a) wrong and b) irrelevant because even if they were right (which I'm not sure of) they were only referring to a tiny number of rapists who are not the major problem for women -the major problem is the "ordinary" type ones, which is what the original article was about.
and dare I say it, Rhubarb did post in a very authoritative fashion which brooked no argument from people who said her characteristics were wrong. And it all got very entrenched and defensive. 
The thing is, if you come on here and post in a very combative fashion and are actually posting factually incorrect things, you surely have no right to be surprised or feel hard done by, when people post back in the same tone. It's kind of inevitable.
