Ultra-conservative politician Fred Nile has lashed out at Sydney 's Mardi Gras celebration , saying parenting not promiscuity should be celebrated . Mr Nile posted this image to his official Facebook account on Saturday , just as Mardi Gras Parade celebrations were getting underway . Marriage equality advocates have slammed an advertisement that aired during Sydney 's Mardi Gras celebrations on Saturday night claiming children from same-sex couples are disadvantaged . 'With so much coverage and celebration of Mardi Gras , it 's important to also be thankful for natural relationships - for the mum and the dad , ' the spokeswoman said . 'Without that traditional relationship , natural reproduction would n't be possible . It 's very important to celebrate natural couples and those values . ' His controversial comments came as an advertisement claiming same-sex marriage disadvantaged children aired on TV on Saturday night . It was organised and paid for by the Australian Marriage Forum , a group 'disappointed with the one-sided debate ' surrounding the issue . The 40-second spot starts with a mother at a park saying : 'We hear a lot about marriage equality , but what about equality for kids ? ' Dr David Gend , president of the Australian Marriage Forum and a family doctor based in Toowoomba , Queensland , says in the commercial that 'so-called marriage equality forces a child to miss out on a mother or a father ' . The Gay and Lesbian Rights Lobby accused the commercial of not only missing the point on marriage equality , but of also attempting to fight a losing battle . 'That 's not equality ; that 's not marriage , ' Dr Gend says . It also asks for supporters to donate money to the group . Marriage equality advocates have slammed the ad , and said the campaign is trying to mislead people on the issue . 'The first point for us is that marriage equality and same-sex couples having children are two different equations , ' GLRL Co-Convenor Justin Koonin told Daily Mail Australia . 'Same-sex couples already can and do have children - marriage equality is not going to change that . 'If the people behind this video were really thinking of the children , they would support marriage equality so that all kids , including those with same-sex parents , could say their parents are married . ' Mr Koonin also said most Australians could see through claims that marriage equality disadvantages children , and that most had 'moved on ' from that discussion . 'They definitely are n't fooling anyone , ' he said . 'If they want to make that claim , have some evidence to support it . 'The majority of evidence shows there is no disadvantage to children with same-sex parents , and in fact most are slightly better off than average . ' Dr David Gend , president of the Australian Marriage Forum says in the commercial that 'so-called marriage equality forces a child to miss out on a mother or a father ' . The controversial Australian Marriage Forum commercial starts with a mother at a park saying : 'We hear a lot about marriage equality , but what about equality for kids ? ' The commercial has been widely criticised on social media , with more than 1200 people disliking the video on YouTube , compared to just 150 who liked it . According to its website , the Australian Marriage Forum is 'an organisation that has been set up to encourage Australians to discuss the issue of same-sex marriage with some discernment and caution . ' It also states marriage equality would 'have enormous consequences on our culture ' and calls for a 'open and honest debate ... free of the intimidation that so many defenders of natural marriage have been subject to in recent years .
