"we have cultures in our midst whose members should never be trusted near children is that right?"

Cultural norms differ. Some traditional cultures have very different beliefs about women and how women should behave. Gender inequality can foster both prejudice against women and the abuse of women, both here and elsewhere in the world.

Indeed we have had plenty of such abuse in this country in the past.

Not ALL abuse of women is rooted in gender inequality, but a proportion is. Education is the key to eliminating abuse that may have it's roots in racist and sexist prejudices, formed from traditional beliefs about the role of women in society and how women should behave.
