Now here’s a surprise: for once it’s the violence-threatener who has backed out.

The headline act of a transgender event in Dundee has pulled out after calling on people to “throat-punch” radical feminists.

Peyton Rose, a transgender singer-songwriter from Edinburgh who was to top the bill at the Trans Pride Scotland event in Dundee next week, posted the tweet last Friday.

Above an image of a leaflet distributed last summer by For Women Scotland, a women’s rights group, she wrote: “If you catch one of these assholes in the act, please undo their work or throat-punch them.”

She deactivated her Twitter account afterwards and has since withdrawn from performing at the event.

A spokeswoman at For Women Scotland said that “gender-critical feminists”, who campaign against people being able to self-report their gender and highlight conflicts between the rights of biological and transgender women, often receive such threats.

Including on the walls of an exhibit at the San Francisco Public Library.

Ms Rose described the tweet as a “tongue-in-cheek comment” written in anger and retracted the use of “terf”, although she declined to say whether she still considered For Women Scotland transphobic. “I have decided not to do Trans Pride and will be taking a step back for the foreseeable future to work on my mental health,” she said.

Saying it was tongue-in-cheek and saying it was written in anger is contradictory. It can be one or the other but not both. If it’s in anger it’s not really jokey.

A Police Scotland spokeswoman said: “On March 19 police in Edinburgh received a report of threats being made via social media and email, and inquiries are ongoing.”

Trans Pride Scotland did not respond to a request for comment.

You astonish me.
