Steve Chapman on the Bogus Threat from Shariah Law

In the 19th century, Catholicism was regarded by many people in this country as thoroughly incompatible with Americanism. They saw it as a hostile foreign element that would subvert democracy. Today, a majority of the justices on the Supreme Court are Catholic, and they are taken to be as American as Mountain Dew. We've come a long way in religious tolerance, writes Steve Chapman. Or maybe not. The belief that Catholics are irredeemably alien and disloyal has given way to the fear that Muslims pose a mortal threat to our way of life.
