I don’t know what the perfect answer is, but I cannot believe that killing every follower of Islam is it.
Our ancestors lived through times when all manner of things were done in the name of Christianity in Europe. Should all Christians have been killed?
During various times in history both Christians and Jews have been targeted for extermination. That didn’t work. I doubt a concerted effort to end Islam adherents would either.
The followers of Islam need to moderate their views and goals. Until they do, I suggest we keep them in their ancestral stomping grounds. This movement of them to Western Civilization is downright suicidal.
I would say that our leaders that push for it are the ones who should be targeted for retribution. What they are engaged in is open flagrant treason.
Prosecute them. Execute them.
When, and if, a people become too civilized to do what’s necessary to survive in an uncivilized world, they simply won’t survive, they don’t deserve to survive, and good riddance.
If you haven’t noticed, survival of the fittest is still being contested here on the third planet, and when you, your family, and your people’s survival are threatened, the proper response in an uncivilized world is to eliminate that threat even if it requires killing every man, woman, and child of the enemy. If you are too “Civilized to do that, prepare to join the Dodo birds.
We didn't have to kill every German. Hell, we didn't kill every Nazi either.
We didn't have to kill every Japanese. We didn't even have to kill every Imperial militarist.
All we have to do is kill enough, in what to them is the most repugnant manner, so that the remainder will understand that to remain a "believer" just ain't worth it.
