Recently two Muslim men were accused in a British court of abducting two teen age girls and repeatedly raping them and then passing them around to their friends. In their defense they claimed that the girls enjoyed it and that they were entitled by their culture to rape non-Muslims especially during Eid celebrations.
This reminds me of the story General Charles Napier who was the English Viceroy in India in the 1850ties. A Hindu priest had come to him to complain about the prohibition of Sati by British authorities. This was the custom of burning a widow alive on the funeral pyre of her husband. After listening to the Hindu priest, General Napier replied,
"Be it so. This burning of widows is your custom; prepare the funeral pile. But my nation has also a custom. When men burn women alive we hang them, and confiscate all their property. My carpenters shall therefore erect gibbets on which to hang all concerned when the widow is consumed. Let us all act according to national customs. No suttee took place then or afterwards"
Of course that was an era in which Western civilization fought for its own survival.
