Anyone who thinks a single-minded fixation on diversity must be the ultimate goal of every human endeavor, including mass murder, is not the sort of person who should be able to buy a gun or to publish his daft ruminations in public forums.

But just to get this straight: Democrats are saying we should be able to jail "strange" or "angry" people, but we can't deplane imams who demand extra-length seatbelts after boarding?

Speaking of which, has anyone else noticed the public expressions of shame and contrition from the Korean-American community after the Virginia Tech shooting? Of course, no one blames this exemplary community for the actions of one nut. The Koreans are manifestly law-abiding and decent -- nipping at the heels of Italians as the greatest Americans and tied for second with the Cubans.

Indeed, I believe this marks the first time a Korean has killed anyone in the United States, not involving an automobile. Nonetheless, Korean congregations, community groups and the family members themselves are issuing statements of sorrow. Not "pleas for tolerance." But sorrow. Remorse. Remember those? They were big back in the day.

If the Koreans can do it, why can't the Muslims? What explains the lack of a Muslim guilt impulse -- so normal, as seen in the case of the saddened Koreans -- after dozens of terrorist attacks on Americans?

How about a Muslim exception to the Second Amendment? That would have prevented the Virginia snipers from killing 10 people within three weeks in 2002. But most important: It would help us achieve "diversity" in our gun law prohibitions.
