I wouldn't welcome any radical group. Especially if they believe in ideas like

Like I said, I don't think anyone should demonize radical feminists as a whole because of such fringe elements.
I know a very nice radical feminist who attends radical feminist meetings. She certainly hasn't told me to strangle myself with my penis yet.
I disagree completely. If a person knows that an act is wrong but does it anyway then they are 100% to blame, even if the victim didn't follow all the possible prevention measures.
We mostly agree here, but let me elaborate on something: it seems to me that preventive measures are different from countermeasures. The former, as their name implies, are supposed to prevent the crime from being committed in the first place. The latter are designed to counter the crime
once it has already been attempted. There is a subtle but substantial difference between the two.
So, for example, encouraging young women to learn a martial art to defend themselves is a countermeasure--it is supposed to fend off the assailant who has already attempted the crime. Since the assailant has no idea beforehand that the woman knows a martial art, the fact that she does will not prevent him from attempting the crime. Instead, it will stop him in his tracks once he has launched his assault.
On the other hand, sitting at home all the time and avoiding any contact with men whatsoever is a preventive measure--a ridiculously unrealistic and oppressive one, since it is impossible for a woman to never leave her home or avoid any and all instances of being in the same place as men. Other commonly espoused "preventive measures" include abiding by certain dress codes, avoiding any friendly contact with men, and gender segregation in public transportion, at work, malls (Saudi Arabia has gender-segregated malls, for example), etc.
The difference between preventive measures and countermeasures is that the former are usually either so unrealistic and oppressive as to be ridiculous or based on myths and untested opinions, whereas the latter actually acknowledge the fact that pretty much nothing will prevent an assailant from attempting his crime when he sees a woman. It's not like a rapist thinks, "Oh, this lady is dressing modestly and acting appropriately. I'm not going to touch her." Only a good knocking out and prison sentence will teach him to think twice about assaulting anyone again.
