Of course it hasn't... Yet those young girls were sexualy and racially abused... As well as the Sikh girls.
Strictly speaking, they were of an age to allow consensual sex. Sure they were vulnerable. Sure they were groomed and plied with alcohol, etc. Sure they were exploited because of their vulnerability.
But there is no suggestion that they were racially abused, as far as I can recollect.
Additionally, I'm sure that such gangs would have exploited Asian, and other BAME girls, had the opportunity arisen, had such girls been allowed to become vulnerable.
In comparison, the abuse that was perpetrated within the Catholic Church and various childrens homes, not to mention the supposed orphanages etc for unmarried mothers, the victims were under age. They were sexually abused by those that were supposed to be caring for their welfare. They were exploited by the very people who had authority over them. And there were vastly more victims, in this country and others, than the victims of grooming by Asian gangs. The number of victims of Asian grooming gangs pales into insignificance, when compared to the number of perpetrators of sexual abuse, not to mention the number of victims, of the various religious organisations.
If we agree that those crimes had nothing to do with racism, why are so many posters so keen to throw them into the discussion about racism?
It's a rhetorical question.
The answer is because they want to excuse and justify racism.
Quite obviously racism predates those crimes by several hundreds of years.
Now which posters keep bringing up those crimes by Asian grooming gangs, as an excuse and justification for racism?
That is another rhetorical question, if you want it to be.
