Nile has also labelled the Greens as being "anti-family", "anti-Christian", and "pagan", citing what he believes to be pro-pornography and pro-sex industry policies and their opposition to the current practice of opening parliament with daily prayers. Nile once described the Greens as the "watermelon party – green on the outside but red on the inside, with a bit of a pink tinge." Following the Moscow theatre hostage crisis in 2002, Nile asked whether the then state minister of police would consider banning full body coverings, like those worn by the Chechen terrorists, from parliament and places of public gathering to prevent the carriage of weapons or explosive devices. Nile has attempted to pass bills in the NSW Legislative Council that would prohibit the wearing of full-face coverings, such as the hijab or niqāb, six times - 2006, 2010, 2011, 2014, 2017, and 2019. Five of the bills failed to be passed, with only the latest bill still not lapsed. On 10 March 2007, Nile raised concern that Australian embassy officials posted in Islamic nations were favouring the immigration of Muslim over Christian refugees. Nile called for a moratorium on Muslim immigration to Australia: "Australians deserve a breathing space so the situation can be carefully assessed", he told an audience in North Ryde. In 2010, Nile asked for the removal of the then Australian Muslim leader Sheik Taj El-Din Hilaly after the sheik placed the blame for sexual assault on the female victims. Nile is opposed to Australian neopagans, having said that the Christian Democrats would "do what it can to stop pagan weddings and witchcraft or Wicca activities." Ethics classes were introduced by the Keneally Labor government as an alternative for children who did not want to attend traditional scripture classes. Prior to the 2011 state election, Barry O'Farrell made a pre-election pledge of not scrapping the ethics classes. Following the election, Nile, who was vehemently opposed to the ethics classes, introduced a private members bill proposing the abolition of the classes at the end of the 2011 calendar year. Debate on the bill was adjourned until 16 September; and eventually Nile was successful in pushing the government to establish a parliamentary inquiry to examine whether ethics classes in NSW schools should be abolished. Meanwhile, in introducing his bill into the Legislative Council, Nile gained headlines by arguing that the ethics course is based on a philosophy linked to Nazism and communism. Nile served on the New South Wales' Parliamentary Standing Committee on Social Issues (1988–1995), facilitating legislative reforms on adoption laws, drug abuse among youth, rape rates and pornography, domestic violence, youth violence, youth rural suicides, compensation for medically acquired AIDS/HIV victims, juvenile justice, births, deaths and marriage records.
