Racism is in the background of this affair - the racism of the Asian men in targeting unprotected white girls. It is a cultural clash of the worst kind.
Many years ago, around 1965, I was dating a Syrian Muslim medical student in Vienna. We were both around 20. I told him I would not have sex with him, which he accepted, but we enjoyed each others company, and would have a kiss and a cuddle.
It ended amicably when i went back home, but I bumped into him a year or so later when i was back in Vienna on a translating job. He asked if he could show me his new student quarters. I went, he locked the door behind me and announced that as a liberated white western girl I had the right to have sex with him, and I'd been ridiculous when we were going out together to refuse this! I was utterly astounded, told him to open the door and let me out. He did so, reluctantly, then (while safely in the doorway) I told him that my rights included the right to say no, the right to not have sex if I chose not to, the right to have my own agenda whatever any boyfriend might think.
I never saw him again, never wanted to, I'm not sure if he even understood where I was coming from, but it did indicate the utterly hopeless chasm between cultures.
This same chasm is evident in those disgusting men. They just cannot see that women and girls have rights, and adults have a duty of care and protection to vulnerable children. Those girls had no value whatsoever to them - they were just objects to be used. The fact they had the freedom to roam the streets, and Asian girls rarely have that freedom, made it all OK in their nasty little racist minds.
PS
That Syrian ex-boyfriend came from Homs. I can't help worrying a little bit about him and his family in spite of his idiocy!
