Now that the smoke has cleared from last month's big shoot-out in the Dade County corral, let's take a closer look at one aspect of Anita Bryant. The lady is, incidentally, a phenomenon- that rarest of rare birds these days: a female entertainer willing to stand up to the vilest and most scurrilous kind of public abuse for the sake of morality, simple decency and Holy Scripture. But it's the "one aspect" I want to zero in on. Anita doesn't want her children taught in tax-supported public schools by sex perverts. Do you?
