This report was produced by the Blatantly Biased Corporation so we do need to take that into consideration. I am sure they have cherry picked the numbers so they can present the US in the worst possible light.
For example Al Beeb is very pro EU but when I look at the statistics in that report they don't compare the US to the EU, which would be a fairer comparison, they compare the US to individual countries. ie France, Germany, Britain. Where is Romania? They are in the EU.
What are they classifying as abuse? ie I am sure the US has much lower rates of female circumcision and forced marriage than Britain or France, but they didn't include those statistics. Of course then again they don't have an accurate accounting of such abuse.
This is just another typical propaganda piece from the BBC. They carefully choose how they make their comparisons in order to support their agenda. Which is. Look how awful America is and how much better things are over here.
