Alibhai-Brown, like the Imam just quoted and all the others, said that there was an over-representation and that their culture was to blame.

I would not know about the culture bit, but I see no reason to doubt them.

It is nothing to do with religion or Islamism so I will not discuss it here.
If you insist on continuing and refuse to use pm, I will start a thread for us so no-one else has to read your shit.
