Ah, so all that birth control is being used by women as protection from aggressive and/or unreasonable men.  And here I am thinking it was just to allow people to have sex without consequences on the taxpayer's dime.  

Ok, you've convinced me.  So let's take the percentage of sex acts that are involuntary and provide that percentage of birth control costs to women via insurance.  But let's be honest; what you're talking about is really an abortion matter, not contraception.  No one takes BC to protect against potential forced pregnancy.
