The Swiss Federal Council wrote in response that in its view, conversion therapies are "ineffective and cause significant suffering to young people subjected to them", and would constitute a breach of professional duties on the part of any care professional undertaking them. As such, in its view, any care professional undertaking such therapies is already liable to be sanctioned by the cantonal authorities. Whether such therapies also constitute a criminal offense is to be determined by the criminal courts in individual cases, according to the Federal Council. Reports emerged in summer 2018 of a therapist claiming to be able to "cure" homosexuality through homoeopathy. He was promptly fired, and an investigation was opened with the Geneva Ministry of Health. According to the Ministry, believing that homosexuality is an illness is sufficient enough to open an investigation. The "Association des Médecins du Canton de Genève" describes conversion therapy as a form of charlatanism. Among the major political parties, the Social Democratic Party (SP/PS), the Green Party (GPS/PES), FDP.The Liberals (FDP/PLR), the Green Liberal Party (glp/pvl) and the Conservative Democratic Party (BDP/PBD) are in favour of LGBT rights including same-sex marriage, adoption and access to artificial insemination for lesbian couples, whereas the Swiss People's Party (SVP/UDC) is generally opposed. Despite its large Catholic and socially conservative base, the Christian Democratic People's Party (CVP/PDC) has become increasingly supportive of same-sex marriage and LGBT rights in recent years. A 2019 survey showed that about 83% of CVP candidates running in the federal election in October were in favour of same-sex marriage. The party supports same-sex marriage and adoption, but opposes access to fertility treatments for lesbian couples. A 2016 poll commissioned by gay-rights organisation Pink Cross found that 69% of the Swiss population supported same-sex marriage, with 25% opposed and 6% undecided. Divided by political orientation, the poll found support at 94% among Green Party voters, 63% among Christian Democrat voters and 59% among Swiss People's Party voters. According to the same poll, 50% of the Swiss people supported full joint adoption for same-sex couples, while 39% were opposed and 11% were undecided. A December 2017 Tamedia poll found that 72% of Swiss people supported same-sex marriage, with 25% opposed. 88% of Greens, Social Democrats and Green Liberals, 76% of Liberal voters, 66% of Christian Democrats, and 56% of Swiss People's Party voters expressed support.
