A rainbow coalition of the disaffected, numbering 10,000 or so, marched from the shacks and open sewers of Alexandra township to the towering complex of chic restaurants, hotels and opulent shopping malls in Sandton, five miles away yet worlds apart. "Factory Gases and Waste are Killing," "Hands Off Iraq," "Globalise the Intifada," "Stop Thabo Mbeki's AIDS genocide" or "Bush, you belong in the Bush" were among banners and T-shirts.
