It's interesting to watch how Islam works. When the Muslims in a non-Islamic nation are threatened by Muslim interlopers, the so-called moderates come forward and claim the only way to save the non-Islamic culture is to impose more Islamic culture (huh). Otherwise the so-called moderates who are supposidly working for the benefit of the non-Islamic host claim the extremists will be enflamed and more violence will be the only possible outcome.
That any civilized nation would even consider such a proposal by a bunch of terrorist thugs indicates the degree to which we've lost sight of western ideals.
Correction: In the above post it should have read "When the hosts in a non-Islamic nation" not "When the Muslims in a non-Islamic nation".
Sorry, the way it presently reads makes no sense.
Actually, trade "sane" for civilized.
The proper response is to persecute them viciously. A sane nation will preserve its borders and culture and destroy invaders that don't assimilate.
