What a year it?s been for the Scientology-watcher. From out of nowhere, the leaderless group Anonymous, the hip new thing among the college-age and computer-literate, suddenly emerged in February to protest L. Ron Hubbard?s wacky ?church.? Tom Cruise?s dim co-religionists, meanwhile, obliged with one hilarious gaffe after another. (It doesn't get much better than Scientology?s New York honcho, John Carmichael, trying to intimidate one protester by telling him?right into a camcorder??I smell pussy!?) Another highlight was actor Jason Beghe?s visit in May to Carmichael?s building on West 46th Street. The Voice tagged along as Beghe was turned away by Scientology?s hired muscle, with youngsters across the street in Guy Fawkes masks chanting: ?I smell cult!? Praise Xenu! Scientology and Anonymous have made ?alternative religion? fun all over again.
