IN the summer of 1956, an angry group of about 50 men wearing black overcoats, black top-hats and shiny black shoes gathered outside the mayors office in West Jerusalem for a protest rally against the municipalitys decision to build a public swimming pool where bare-bodied men and women would be allowed to mingle freely. These protesters were members of the Haredim, a community of ultra-orthodox Jews. Back then, the small Haredi community,with its idiosyncratic dress and conservative lifestyle governed by the Torahthe Jewish scriptureswas on the margins of civic life in West Jerusalem. And while the protest attracted curious pedestrians and a few columns in the local papers, the swimming pool was built and life went on as before in West Jerusalem. Now, however, the Hare-dim is increasingly gaining in popular following and political clout. Five years ago, the Haredim launched a campaign against immodest billboards put up by the Poster Media Company. This time, however, verbal condemnations gave way to arson, and across the city bus stops that exhibited the posters were burned down. But instead of insisting on its rights, the firm reached a compromise with the Haredim and toned down its posters.
