Let me put it simply for you.
Like you, Lox and Jim, I know little about Pakistanis.
Like you, I am not qualified to form an opinion about them or comment on one.

Like 5 year olds, you keep asking me for something I can not give.

What I can do is discuss the evidence for the over-rep.

Here is some.

When a campaign was targeted at the BP community in Blackburn, the incidence of this kind of child sexual abuse was eliminated.

The journalist Bindel in a rigorous investigation found large numbers of girls who had been abused by BPs, but none by other groups.
The German video report, no longer on YouTube, found exactly the same.
Jack Straw spoke about his own personal experience and contact with victims.
Ann Cryer said she had the same experience in her constituency.
The Dando Institue report on On-Street Grooming By Gangs, that has resulted in at least two follow up studies of On-Street Grooming By Gangs, that found 95% BP perpetrators.
Hilary Wilmer with her hundreds of cases, all BPs.
She corroborates all the previous.
Senior police officers, serving and retired.
Shafiq, Allibhai-Brown and Ahmed all tell the same story from BP perspective, and it corroborates all that has gone before.
Hindu and Sikh organisation who report hundreds of their girls have been victims too.
Perpetrators, all BPs
