From American Thinker.  A rational look at Muslim immigration.

AN ANALYSIS OF DILBERT'S PERSPECTIVE ON MUSLIM IMMIGRATION

This highlights Scott Adams's point about the motivation of an individual.  Harold Bloom has explained that "Islam is the only superorganism with a meme team – a worldview and a 'total system of life' – built for global rule by its founder. Islam's ... advantage is the eagerness of its militants to solve political disputes with violence. Violence is a potent force multiplier, especially in a world peppered with democratic societies. The chant among young Muslim jihadists is, 'We love death more than you love life.' Why? Because those who die killing unbelievers have an express ticket to fame, sex and paradise. The result: suicide bombers."

Toward the end of his blog post, Scott Adams asserts that "[i]t is nonsense to argue about whether our Muslim immigration policies are good or bad without the benefit of knowing where the tipping point is, if such a thing even exists.  My guess is that the pro-immigration people and the anti-immigration people would agree we shouldn't go past the tipping point.  But if neither side knows where the tipping point is, you can't call the opinion on either side sensible."  Thus, "[t]he so-called sensible people in the middle (including me) have opinions that are effectively nonsense because we don't know where the tipping point is."

If a destructive value system is permitted to metastasize without any counterbalancing, the question of a tipping point eventually becomes a moot point.  The sensible inquiry is not how many Muslim immigrants should be permitted to enter a country; the real question is, what is their motivation, and what values do they want to impose on the host country?

Andrew C. McCarthy notes, "How do we embrace our Islamic friends while excluding our sharia-supremacist enemies? To fashion an immigration policy that serves our vital national-security interests without violating our commitment to religious liberty, we must be able to exclude sharia supremacists while admitting Muslims who reject sharia supremacism and would be loyal to the Constitution."
