Gideon studied law at the University of Warwick, building up the JSoc whilst fighting off opposition within the Students’ Union. He was elected Anti-Racism Officer for the student body and appointed to the Race and Religion Incident Review Panel of Warwickshire Police and West Midlands Police’s Key Individuals Network. He graduated and returned to London in 2005. In 2009, he reported and pressed charges against the then head of the Foreign Office’s South Asia Group for antisemitic hate speech. The conviction was later overturned on appeal.
In the summer of 2014, as fighting flared between Hamas and Israel and antisemitism peaked in Britain, he joined Campaign Against Antisemitism. He was the principal organiser of Campaign Against Antisemitism’s major rally outside the Royal Courts of Justice calling for zero tolerance law enforcement against antisemitism. Gideon was elected Chairman of Campaign Against Antisemitism in autumn 2014, a duty which he performs as a volunteer.
Gideon has spoken at the House of Commons and given evidence to the House of Commons Home Affairs Committee. His work for Campaign Against Antisemitism has been publicly praised by Theresa May. In 2014, Gideon was named by The Algemeiner as one of the “top 100 people positively influencing Jewish life”.
Gideon has worked in high-tech, commercial real estate and management consultancy. His business manufactures electronic equipment. He serves on the board of the Jewish National Fund UK.
