On Saturday, more than 1,000 fans of Chinese dissident Ai Weiwei marched through Hong Kong demanding his release. Weiwei's arrest is seen as part of a major crackdown on dissidents in the People's Republic of China, which fears an upheaval similar to those in the Middle East. On Easter Sunday, more than 20 Chinese Protestants were arrested in Beijing while trying to attend an open-air service (CLICK). Hong Kong is much more relaxed about dissent. Since the British handed it back to China in 1997, it has been run as a special administrative region with its own government and a high degree of autonomy from China, except for foreign relations and military defence. Unlike China, it has a thriving erotic film industry. Its latest success is Sex and Zen: Extreme Ecstasy, which beat Avatar at the box office (CLICK). Note the "LOVE IS ALL" T-shirt below the Weiwei mask. Might a combination of peaceful protest and erotic movies be the new opiate of the masses?
