SURREAL DIVERSITY: Just when you thought multiculturalism had already reached the outer limits of the ridiculous, along comes the L.A. Times to celebrate all the marvelous ways in which the "differences" that characterize the individuals still missing in London mirror the "differences" of London's population: "List of Missing Is as Diverse as London Itself." One reads this article with the faint hope that the writer is attempting satire, but no: We are to use this solemn occasion to further divide democracy into demographic subgroups that reflect the limitless narcissism of multiculturalist activists. At the risk of sounding completely irrelevant, here's a passing suggestion. Suppose we agree to think about the London missing in terms of what they had in common: Good and decent people were going about their lives when brutally assaulted by irredeemable cowards and sadistic criminals. If this is a time to celebrate how we're "different," let this be the distinction we bear in mind.
