Trans extremism is a one-way street. Male bodied self-identifying trans criminals have been permitted to serve time in a female prison, but it doesn’t seem to work the other way around.

A 33-year-old transgender man who was convicted of kicking a young dog to death has lost his appeal to be housed in a male prison instead of a women’s prison.

Simon John Cromwell was convicted of an animal cruelty charge in the Broken Hill Local Court in July, after killing a former friend’s Staffordshire terrier, named Olaf. 

He was sentenced to nine months’ jail, with a non-parole period of three months, but appealed that sentence. However, his appeal was dismissed in District Court this week. 

His defence attempted to get Cromwell housed in a male prison, but the judge refused.

Judge Pickering said that, while he could empathise with some of the potential difficulties Cromwell might face in a women's prison, he was not going to comment on where NSW Corrective Services decided to place the transgender man.

Previously, transgender axe attacker Evie Amati was housed in a female prison despite being biologically male.

There are reportedly 400 transgender prisoners in jails around the nation. 

Binary spokeswoman Kirralie Smith said transgender criminals need their own spaces.

“Simon Cromwell is most likely on testosterone and could pose a threat to female prisoners,” she said.

“Placing a biological female, even though she appears male, in a male prison has the potential for great harm.

“If criminals appropriate the opposite sex they would be best served in spaces with each other rather than putting other inmates or themselves at risk of greater harm.”
