Watch on SFlix. This Kiss-In took place the evening of April 29, 1988. It was cold and pouring rain, but the demonstrators soldiered on. The Kiss-In was a favorite tactic of ACT UP because it defied the homophobia of the larger society, demonstrated a lack of fear and stigma around AIDS and fostered camaraderie among the demonstrators and within the group as a whole. It was also a whole lot of fun, which is evident from the footage.
