Mark Krikorian, who we last saw bashing naturalized Americans and the children of immigrants in order to argue that the United States should close its borders to immigrants, is at it again. On Monday, to make his case for reducing future immigration, he warned against Islam and Muslims living in the United States.

Writing on the website of National Review, Krikorian attacked Islam as “a unique danger to our Republic” and advocated for “the use of undercover agents to infiltrate” mosques and Muslim organizations “and track their activities.” He concluded: “If a large and growing Muslim population represents a threat to liberty -- and I believe, with [Herman] Cain, that it does -- then that's yet another reason to reduce future immigration.”

From his July 18 blog post on National Review Online's The Corner:

I'm the last person to defend Islam, and I'm not doing so now, but Cain is clearly wrong. Yes, of course, Islam is more than just a spiritual system -- it's also a political system, a system regulating economics, war, the subjugation of infidels, personal hygiene, and every other aspect of life. And of course radical elements -- i.e., orthodox Muslims -- are behind the construction of many, if not most mosques in the West. Both of these facts make Islam a unique danger to our Republic and are arguments for enhanced scrutiny of mosques and all Muslim organizations, the use of undercover agents to infiltrate them and track their activities, a resumption of the use of ideological exclusion in visa and immigration matters, and the categorical rejection of all special demands, whether wearing a hijab in a driver's license photo or giving legal authority to sharia courts in family-law matters.

But -- if Muslims want to build a gathering place, consistent with normal zoning and fire-safety laws and the like, where they just worship and break bread with their fellows, they have every right to do so; suggesting otherwise is dangerous folly, cutting down the law to get after the devil. If a large and growing Muslim population represents a threat to liberty -- and I believe, with Cain, that it does -- then that's yet another reason to reduce future immigration. But once you admit people, we're bound to judge them individually, by the same yardstick we use for everyone else.

Krikorian previously asserted that the only way to produce " 'moderate' Islam" in countries like Iran is to wholly separate Islamic societies from the West and allow a “tsunami of violence” to overtake the people living under “Islamic regime[s].” Indeed, while discussing the future of Islam in an NRO post, Krikorian wrote that Islam is “a failure as an ideology and way of life in the modern world,” adding that "[o]ur long-term strategy, then, should be to create two, three, many Islamic republics, each one inevitably an example of Islam's bankruptcy."

Despite his extremist views about immigrants and his anti-immigration stance, numerous media outlets, including NPR, The New York Times, and ABC News, believe that Krikorian is a worthy voice in the immigration reform debate.
