""Now, I will be the first to admit that this argument could be wrong. My figures could be up the wall for umpteen reasons and I would love someone to prove me wrong. Can anyone do that?""

The only issue I would take with that is that you need to widen your approach.

You are equating these cases with cases of paedophilia and they are not necessarily the same. You would need to know how many young females are working as prostitutes, having been groomed in exactly the same fashion by non Pakistani, non Muslim males, and factor them into your calculation.

This figure is simply not available, so your comparison fails.
