Politician 'guarantee' legalising same-sex marriage will lead to polygamous relationships

A former Queensland minister has revealed he will vote 'No' on the same-sex marriage postal plebiscite because he believes it will lead to other types of relationships wanting the same rights.

Bill O'Chee, a past Nationals MP says legalising same-sex marriage will result in people involved in polygamous arrangements demanding they are recognised in Australia because they will argue it is of the same oppressive mentality.

'I cannot see how you can defeat somebody saying if you have gay marriage why cant we have polygamous marriage,' Mr O'Chee told Daily Mail Australia. Mr O'Chee claims he is educated to speak on the topic because his Chinese grandfather had two wives.

His grandfather was unable to bring both women legally into the country as his partner, and it wasn't until his Australian resident wife died that the second woman could immigrate.

'I think my grandfather was selfish and what he did was unfair. They were creating a situation where we reward selfishness and unfairness,' Mr O'Chee said.

He says legalising same-sex marriage would open up a 'Pandora's Box that we can never close.' He says not only can he 'guarantee' legalising same-sex marriage will lead to polygamous relationships demanding the same rights, but it could lead to stepbrother-stepsister and foster brother-foster sister relationships.

'If marriage is all about love, shouldn't these people also be allowed to marry too? 'It would be almost impossible for a court to reject a claim that laws against polygamy weren't discriminatory.'  Love and love alone isn't reason enough to justify equal marriage rights, citing his grandfather's marital circumstances as evidence of a breakdown in that thinking.

He says despite being a practicing Christian, he 'would have arrived at the same conclusion' had he not been. Mr O'Chee will be voting 'No' in the upcoming postal plebiscite.
