Where do these Right Wing ideas come from in regard to 'acceptable moral social content' regarding aggression and violence?

While mayor, Wasilla charged rape victims for rape kits. (Sep 2008) 

A rape kit is a tool of law enforcement.  It is absolutely necessary for the conviction of a rapist.  To demand a woman, THE VICTIM, to be responsible for the cost of a Rape Kit is detrimental to the woman, the police, the prosecutor and THE LAW.  

I mean, why not just let the rapist walk, okay?  A rape kit is NOT a medical treatment and quite frankly even if it was, the 'Victim Witness Law' of most states would cover it and the therapy for recovery after the crime was committed.
