December 1989 was one of the coldest months on record in the New York area. The month is also remembered for an audacious protest organized by the AIDS activist group ACT UP whereby thousands of its members disrupted Sunday morning Mass at St. Patrick's Cathedral on December 10 to protest the Roman Catholic Archdiocese of New York's stand on sex education and condom distribution in the wake of the AIDS crisis.
And although this demonstration was perhaps the boldest of any ACT UP protest, others generated considerable publicity as well, e.g. on the floor of the New York Stock Exchange; at the FDA in Washington; at Hearst Publications (protesting an article in Cosmopolitan); at Grand Central Station; and on the sets of CBS Evening News w/Dan Rather and PBS' MacNeil-Lehrer Report.
To learn more about the vital role ACT UP played in the fight for improved healthcare and medications for HIV/AIDS sufferers the book Moving Politics: The Emotion & ACT UP's Fight Against AIDS is a worthwhile read.
