Trans campaigners have criticised “anti-trans bigots,” after a number of “disgusting” phallus-shaped stickers – carrying the phrase “women don’t have penises” – were found across London, including on Stonewall’s office building.

A Twitter user posted images of the stickers on Sunday (August 5), which were also shown stuck onto an electrical box outside the offices for The Guardian and The Observer, and on an advertisement board showing a painting of Elizabeth I for the National Portrait Gallery.

Responding to the images, Sarah Brown, a member of Stonewall’s Trans Advisory Group and a trans woman, told PinkNews: “These stickers are puerile and disgusting. There is a strong push to demonise trans women in the UK and I really worry where it’s going.”

A Stonewall spokesperson told PinkNews that the sticker had been removed from the office building in Clerkenwell.

The Twitter bio for the user who posted the images, called Anne Ruzylo XX, includes the hashtag #GetTheLOut, which is affiliated with controversial anti-trans group Get The L Out. The user has also tweeted in support of the group.

However, Get The L Out told PinkNews that it was not responsible for the stickers.

Owl, a non-binary trans activist and filmmaker, condemned those behind the stickers, telling PinkNews: “This is comparable to teenagers trying to be funny and drawing penises everywhere – it’s incredibly immature, childish and just ridiculous. It just continues to show that this these fringe groups of ‘activists’ are desperate and slowly unraveling with their ‘activism.’ Read more via PinkNews
