The anti-same-sex marriage campaign which launched in Australia has been mocked as its brand is the colours of the bisexual flag.

The coalition for marriage is a conservative campaign group fighting for a No vote on the same-sex marriage postal survey which is due to go ahead in Australia.

The coalition is made up of the Marriage Alliance, the Australian Christian Lobby and the Christian Schools Association.

Each group is a staunch opposer of marriage equality.

As the campaign launched, they warned of the apocalyptic “consequences” of a Yes vote.

Some of those consequences include “gender-bending, politically correct programs like Safe Schools”, which they staunchly oppose.

They have prided themselves on being the “silent majority” and “freedom of religion”.

However, the collection failed in one area of their hatred for the LGBT+ community

In their branding.

The logo of the coalition for marriage is built entirely around the colours of the bisexual flag.

While the coalition for marriage probably didn’t realise it, many LGBT+ activists definitely did and have been mocking the group online.

“The newly merged No campaign – the Coalition for Marriage – literally have the Bi Pride Flag as their logo,” one person wrote.

Somebody else added: “Not the best use of the Bisexual Pride colour scheme but ok….”

A third wrote: “Oh @LyleShelton that is a FABULOUS website. So pretty and flamboyant!!”

A postal vote on same-sex marriage will go ahead unless a lawsuit in the High Court is successful.

It comes after a lawmaker in the majority Liberal Party failed to pass a Parliamentary vote.

Lawmakers then attempted and failed to revive a plebiscite bill in the Senate.

Many feared that the postal vote would become a “hate speech bonanza” as the vote is being conducted by the Australian Bureau of Statistics, rather than the Australian Electoral Commission.

This means that the vote is not subject to the Commonwealth Electoral Act’s prohibition on the use of any malicious or deceptive material.

Special Minister of State Mathias Cormann is putting forward legislation which will force the Bureau to abide by the Commonwealth Electoral Act, which prohibits the use of any malicious or deceptive material.

Labor’s legal affairs spokesman Mark Dreyfus suggested Labor’s support for the special law, saying “our inclination is to make sure that this is a respectful debate”.

However, Dreyfus said that the party would need to see the legislation before supporting it.

“If the government won’t stand up to the disrespectful and misleading and offensive things that have already been said – we gave Malcolm Turnbull an opportunity in the Parliament last week to condemn for example Bronwyn Bishop’s appalling comments.

“He didn’t. If the government won’t do that, perhaps we do need to look at other measures,” Dreyfus added.
