From reading the article in the Guardian it seems to me that sex traffic is a world-wide
problem and not limited to any cultural group or gang. To narrow the issue it so that it fits the present xenophobia regarding Muslims is specious and destructive.

Any mention of Pakistani or Muslim groups today are subject to the same kind of
baiting that was used in earlier times to refer to African-Americans regarding white women being molested (history of the KKK and Reconstruction ala DW Griffith's "Birth of a Nation") and is based on fear and demonization and a long legacy of this sickness.

The point of the Guardian article as I see it is that it doesn't point to these incidents
as being exclusive to any one culture.

Racism doesn't explain anything.
