An American trans activist accused of sending death threats to Joanna Cherry, Rosie Dufield, and Neale Harvey, a Scottish Members of Parliament (MP), has been revealed to be New Jersey trans-identified male Sean Johnson.

Johnson identifies as a woman and goes by “Sylvie,” according to Reduxx. Johnson has uploaded videos to PornHub.

The report noted that Johnson has repeatedly made mention of his "girldick," a term used to caption and identify the explicit content uploaded to the porn website.

Johnson is also known to go by "Bellatrix" in his explicit material, an "ironic" reference to one of JK Rowling's characters in the Harry Potter series. Johnson <a href="https://web.archive.org/web/20220901032339/<blockquote class=" twitter-tweet"="">mentioned"> the hopes that Rowling would take offense. Johnson said he hopes it "disgusts her to have a trans woman go by her character's name."

According to the report, Johnson is "violently opposed" to single-sex services and measures to protect women's privacy. He also uploads his explicit material "as a woman" on PornHub.

Johnson allegedly sent threats on social media to three UK politicians who are known to be critical of gender ideology. The report noted that the authorities initially refused to investigate the spat of menacing posts online, but they have since reversed course. They will now be looking into the tweets under the Communications Act of 2003.

Cherry posted a screenshot of two of the messages that Johnson posted on Twitter, saying: “I am hoping the Metropolitan police will reconsider their decision on the criminality of the first tweet threatening to kill me in the light of the second tweet threatening not just my life but that of 2 other MPs @RosieDuffield1 & @JNHanvey.”
