Don,
1. Several other ethnic groups in this country have exactly the same cultural mores as Pakistanis (Indian, Sikh, etc.), yet have no such problem with their young men.

I don't know Don.
Lively has pointed out that other groups are involved in this crime though.

2. Out of 1.2 million British Pakistanis, only a handful in a very confined area of the country have been found indulging in this "cultural" aberration.

Agreed Don.

3. As has been said before, your claims of over representation stem from skewed statistics which no genuine mathematician would adduce as even indicating, much less proving a conclusion.

I dispute that Don.
There are hundreds of victims who say BPs were the perpetratores.
I have heard of none saying otherwise.

4. Even were the statistics more solidly based, any over representation cannot possibly support your "cultural effect" theory.

Agreed.
Any theory should seek to explain the over-rep, not the other way round.
That theory does do that.
