Bill shorten has backed a Labor candidate who shared porn and rape memes and insulted working class voters on Facebook. Luke Creasey, 29, has refused to step down as Labor's candidate for Melbourne after it emerged he made offensive posts in 2012. At a press conference in Macnamara, Victoria on Friday morning, Mr Shorten implied Mr Creasey was too young to be held responsible for the posts. The Labor leader said: 'I'm not going to defend the remarks. [They were] shocking and stupid. 'He has also come forward and said he was 22 at the time, seven years ago. He is mortified, as he should be. 'He doesn't want to cause any embarrassment and he doesn't hold those views now. He has apologised deeply and he certainly doesn't hold those views now.' Rape jokes: Luke Creasey, 29, has refused to step down as Labor's candidate for Melbourne In the posts in 2012, Mr Creasey shared one meme titled 'overly attached girlfriend' which read: 'Hey I just met you / If you don't date me / You'll go to prison / I'll say you raped me.' Another meme he shared, designed to insult people with concerns about immigration, said: 'Complains refugees waste tax dollars / Uses Centrelink money to buy drugs and alcohol.' Mr Creasey also insulted working class voters in Scott Morrison's south Sydney seat with a post that read: 'Endorsement by those who call the Sutherland Shire home is not something that anyone with decency should aspire to.' He also shared a link to porn involving the sexual kink pegging. Greens MP for Melbourne, Adam Bandt, demanded Mr Creasey's resignation. 'Just a few years ago, while I was representing Melbourne's values in Parliament, my Labor opponent was sharing rape jokes,' he said. 'Violence against women in any circumstances is unacceptable. I think Mr Creasey needs to reconsider whether he remains as the Labor candidate.' At the conference on Friday morning, a reporter asked Mr Shorten: 'At what age does the young and dumb defence cease to apply?' The Labor leader replied by turning the attack on the Liberal Party after Tasmanian candidate Jessica Whelan resigned on Friday over Facebook posts calling for Muslim women to be mutilated and sold into slavery. 'No, I agree. Stupid is stupid is stupid. I'm not here giving the bloke a pat on the back,' he said. 'But let's go the contrast. The Liberals have been forced to dump another one of his right-wing candidates… Jessica Whelan said what she believes now. It reflects on what she thinks now.

'He understands – he doesn't think that now. He certainly doesn't think it at all.' Ms Whelan was accused in Parliament of advocating the genital mutilation of Muslim women and selling them as slaves, and of saying Tasmanians 'don't bloody want' to take in Syrian refugees. She has strenuously denied making some of the posts but admitted to others and stepped down as the candidate on Friday. Ms Whelan is the latest of a string of candidates at the federal election to be in hot water over online posts. On Wednesday, two Liberal candidates were dumped over online posts - one for homophobic remarks and the other for anti-Islam rant.
