We can afford to lose our blue zones, they are cess pools anyway. Let the Islamists have NY/LA/DC and impose Sharia Law on the liberals who may then change their tune when heads are rolling down 5th Ave.
The rural folks know how to take care of a problem like Islamists. Shoot shovel shut up.
Sounds good on the surface. However, the libs would leave the cities and start fouling the rest of the country with their values.
