rulings, such as: It is constitutional for public funds to provide parochial school pupils with transportation to classes--but not field trips. To provide parochial schools nurses--but not guidance counselors. To provide religious schools with books--but not maps. This last bit of judicial casuistry made Pat Moynihan wonder: What about atlases--books of maps? It has been well said that really up-to-date liberals do not care what people do, as long as it is compulsory. Many liberals are ``pro-choice'' only about killing unborn babies. Not about owning guns, driving large cars, wearing fur, smoking cigarettes, privately investing a portion of their Social Security taxes, saying the unedited (by the U.S. Court of Appeals for the 9th Circuit) Pledge of Allegiance, and on and on and on. The opposition to school choice for the poor is the starkest immorality in contemporary politics. It is the defense of the strong (teachers unions) and comfortable (the middle class, content with its public schools and fretful that school choice might diminish their schools' resources and admit poor children to their schools) against the weak and suffering--inner city children. Happily, on Thursday, socially disadvantaged children had their best day in court since Brown vs. Board of Education in 1954.
