Goodbrad, i think history is the greatest evidence with the Japanese "comfort women" throughout china and SE Asia including many Dutch women from indo.
They were raped daily for 2 years up to 10-20 times a day.
The Japanese were brutal and Isis are just plain animals so why wouldn't this be the truth.
Look how many western jihadis are conned into a lie so no doubt women woukd be targeted too.
