I'm just guessing here but the experience of those white girls in Rochdale/Rotherham/Oxford etc. would probably be worse than anything the vast majority of non-white girls in this country, in this time period, have suffered at the hands of men of a different race.
If we're going back in history, then mixed race people have now got as much to answer for as white people because they're just as likely to be related to people involved in the slave trade. It's a silly game of oneupmanship that doesn't achieve anything.
Until it's recognized that white people can be and have been victims of racism and exploitation then we'll probably never move on to the next step, which would be to call out the real b@$turds in this world. It's the 1% that we need to be dealing with, all of this racism etc. is a very convenient distraction for them. I think we're all being played.
