Hinduism and LGBT topics: Hindu views of homosexuality and, in general, LGBT (lesbian, gay, bisexual, and transgender) issues, are diverse and different Hindu groups have distinct views.  Homosexuality is regarded as one of the possible expressions of human desire.  Although some Hindu dharmic texts contain injunctions against homosexuality, a number of Hindu mythic stories have portrayed homosexual experience as natural and joyful.  There are several Hindu temples which have carvings that depict both men and women engaging in homosexual sex.  Same-sex relations and gender variance have been represented within Hinduism from Vedic times through to the present day, in rituals, law books, religious or so-called mythical narratives, commentaries, paintings, and sculpture.  The extent to which these representations embrace or reject homosexuality has been disputed within the religion as well as outside of it.  In 2009, The United Kingdom Hindu Council issued a statement that 'Hinduism does not condemn homosexuality', subsequent to the decision of the Delhi High Court to legalise homosexuality in India. .  The Supreme Court of India subsequently overturned the capital high court's decision in a move cheered by domestic Hindu groups in India such as the influential right-wing RSS, which concedes it should be "kept to the bedroom," does not believe it illegal but immoral as it is considered a rare condition
