I was responding to your comment that those are not "effective strategies".  
You know that no one strategy is going to end rape and assault against women.  Instead of marching and lawsuits, you propose kicking as a more effective strategy.  Women have probably been kicking men for millennia, with little to show for it, other than often being beaten even more by the men who were already assaulting them.   
I think that the only way to really diminish the incidence of abuse against women is to change the societal perception that this is somehow OK -- at any level.  To do this, many strategies need to be employed.  
While self-defense is important, it's also important for women to remember that, in cases of assault, they need to preserve their lives and minimize harm to themselves.  Fighting back is often not helpful.
