This is flagrantly untrue https://en.wikipedia.org/wiki/Rotherham_child_sexual_exploit...

I think OP is referring to stuff like the Rupert Lowe’s Rape Gang Inquiry

TBF they are real, but are they isolated to one ethnic group? No. Are the victims as numerous as Rupert Lowe's report makes it out to be? No.

Epstein and grooming gangs are both real. Not that the whole "grooming gangs" problem hasn't been vastly amplified and turned into a repeated media talking point by a bunch of the extreme right wing in the UK, however. There's plenty of domestic non south asian pedos and molestors there too.
