the demonstrators demanded an end to heteronormativity and consciously defined themselves as anti-bourgeois. Some wanted to fight against any State discrimination, not just against LGBT people. Unlike today, the demonstrations had an almost exclusively political character, and were followed in the evenings not by partying but by political discussion. 1982: The AIDS crisis In 1982, the first news of AIDS reached Switzerland. The first names given to it were "gay cancer", "gay disease", and "gay-related immune deficiency" (GRID). No-one knew at the time what caused AIDS, or how the infection spread. The advent of AIDS changed the movement of the mid-eighties completely. Many of the founders died, and LGBT people were stigmatised, leading to CSDs and gay rights demonstrations becoming sporadic rather than annual. To meet this challenge, the Schwulen Medizinmänner (Gay Medicine Men) group was founded in 1984 (renamed Medi Gay in 1997), and led the first information sessions on HIV and AIDS in the same year, together with HAZ, SOH, and the University Hospital of Zurich. In 1985, ‘’Loge 70’’, all ‘’HA’’ groups, ‘’SOH’’, and the Federal Health Office (BAG) founded ‘’Aids-Hilfe Schweiz’’ (AHS) (AIDS-Help Switzerland). In 1986, the AHS published an AIDS information brochure, which was distributed to all households in Switzerland. The AHS prevention campaign is the most successful prevention campaign in Switzerland. CSDs resumed in Zurich in 1986, and in Bern in 1987. The 1987 Bern demonstration was more a protest against the withdrawal of a permit by the city authorities for a gay camp, than a gay pride parade. In 1988, the culture Kaserne in Basel, there was an exhibition of Men's Stories about Gay Life in Basel, 1930–1980. The population began to perceive LGBT people outside of the subject of AIDS again. The show was such a success that a profit was generated, with which the Stonewall Foundation was founded, which funds the CSD-Stonewall-Award (see below). In 1989, a Christopher Street Day was held in Zürich with a cultural program to mark the 20th anniversary of the Stonewall riots. Despite the suffering that HIV and AIDS brought to many people, it also brought a broad understanding of alternative ways of life in Switzerland. Authorities and the gay rights movement worked successfully hand in hand. 1990s Pride festivals CSDs have again been held annually in Zürich since the 25-year anniversary of the Stonewall riots in 1994, now with a cultural program. In the 1990s,
