Ironic humour in online forums, including racist jokes and antisemitic conspiracy, is broadly considered to be a starting point for young white men who become radical supporters of white nationalism.

Despite the seriousness of the allegations he faces, the soldier has continued to engage in white nationalist rhetoric online. 

Last month Stuff revealed that a Twitter account credibly linked to the soldier was activated on December 31, 2019, two weeks after his arrest. 

For more than a month the person behind the account posted racist, homophobic, and antisemitic comments, including references to a "white genocide" conspiracy theory.

"Even if we are to witness the end of our people, at least we had the privilege of being a part of this amazing journey our people set out on so many thousands of years ago," the account posted. 

The account also describes being arrested and detained for having "IRL" (in real life) alt-Right friends, and for committing a "thought crime".

The Defence Force has refused to answer questions about the man's open-arrest conditions and whether he is permitted internet access.

The soldier – who a source says was headed to Russia for Christmas before he was detained – is being held on open arrest at his home outside the wire of Linton Military Camp, awaiting a court martial hearing.

The Manual of Armed Forces Law specifies open arrest as involving "such restraint as may be necessary to ensure a continued presence ... The member is to attend such parades or musters as may be required. The member is not to consume alcohol. He or she may perform his or her normal duties".
