Paul Mirengoff of the Powerline blog makes a good common-sense case for stopping all immigration from certain Muslim countries which seem to breed terrorists once they live in our country for a while. He argues that no amount of pre-immigration vetting is going to root out the bad guys ... see:
Powerline Blog. Sayfullo Saipov was the immigrant from Uzbekistan who slipped through the supposed "rigorous two-year" vetting process (according to the lefty pols and media) and went on to slaughter eight and injure eleven with a rental truck in New York City this past Halloween. (Perhaps, if the two-year vetters had noted that his first name translates into "sword of Allah", it might have helped.)
Yes, our bubble-headed left ... who believe that "diversity" and "inclusion" are the panaceas to all our nation's problems ... have allowed ideology to cloud their common sense. When the United States was building the Panama Canal, we realized that mosquitoes,which caused yellow fever and malaria, were a major hinderance to this project. So, we reduced the population of the mosquitoes by eliminating and oiling their breeding grounds.
This is, what we used to call common sense. And common sense dictates that, if we want to reduce terrorism in our country, we should stop all Muslims from immigrating from those countries that seem to spawn such miscreants. Just as all misquitoes don't carry yellow fever or malaria, not all Muslims are potential terrorists. But, not being able to filter out the bad ones, the next best solution would be to un-diversify and un-include those Muslims who might become our killers. It is just that simple ... use that sense which causes us to come in out of the rain.
No, I am not calling Muslims (from these suspected countries) "mosquitoes" (an expected knee-jerk response from the left). I am saying that, unless and until we can find a way to keep such Muslims from turning on us with the sword of Allah, we should not invite them into our homeland in any numbers. Someday, perhaps, after there is a reformation within this "religion of peace," then this stricture can change. But encouraging people who might want to murder or enslave us does not seem too common-sensical.
