And you have scientific, empircal, evidence to support your contention? Not just "it was the pakis/indians/mussies wot done it" conjecture.
I'm not denying that criminals of whatever ethnicity or religion will prey on vulnerable girls. They will also prey on vulnerable young men/boys (and I suppose if you're AK young goats), but to suggest (as you do) that only "third worlders" (WTF does that mean?) exploit the vulnerable is shoddy thinking at best and fuzzy logic at worst.
