Well, the ones that attend MOSQUES is a good starting point for the sorting...
It's just like in the Military's "Don't ask...Don't tell". Allow me to explain....
If you suspect a recruit is gay....you say "Clang-Clang-Clang!". If they finish with "...went the trolley", you found one!
With these Islamazis it's "Allahu....". If the finish with "Akhbar!", cuff 'em and DEPORT!
Just rounding up and deporting illegal muslim aliens, would be a good start.
