A white supremacist who idolised Adolf Hitler has appeared in court for a terrorism offence and for posting racist, Islamophobic, homophobic and anti-Semitic calls to arms on social media.

Sean Creighton, 45, told police that he was “a bit of a hater who hated for the people”, Kingston Crown Court heard.

He posted an image of Adolf Hitler along with the message “kill the Muslims” online.

Prosecutor Jonathan Sandiford told the court: “The defendant was a committed racist, a member of the National Front.

“He was enthralled by Nazism and Adolf Hitler whom he told police in his interviews was his God.”

Creighton also had an electronic document entitled “White Resistance Manual 2.4” which contains details of shotguns, improvised weapons and explosives, and harassment.

Mr Sandiford described it as a “complete guide on how to prepare for and conduct a terrorist campaign”.

Authors of the document said they want to exacerbate existing tensions, to smash Jewish power and influence, destroy the legitimacy of government and punish white people who have committed acts of treason against their own people.

Creighton, of Enfield, north London, has pleaded guilty to eight offences, including a terror charge of collecting information which could be useful to someone committing or preparing an act of terrorism.

He has also pleaded guilty to six counts of publishing or distributing materials that were likely to stir up racial hatred and a further count of possession of racially inflammatory materials.

The court was told that Creighton’s actions showed links to and support for various groups such as neo-Nazi organisation Combat 18, National Action and Aryan Strikeforce.

Among the other posts he put on social media is an image of a gun alongside a Swastika and the words “Jews prepare to die”.

Creighton also posted an image of an injured man alongside words intended to stir hatred of sexual orientation as well as a cartoon of a head in a noose, the court heard.

He also had stickers from Combat 18 with the text “sink the refugee boats!”.

Creighton also posted a “threatening, abusive or insulting” image of a man holding a rifle in front of a black child.

The court was told that Creighton posted material to his 692 followers and that he had suggested no harm was done because he was contacting people who had similar views.

Judge Peter Lodder QC, the honorary Recorder of Richmond Upon Thames, adjourned the hearing until 10am on Thursday when Creighton will appear in custody for sentencing.
