As the MSM cannot resist calling out Tommy Robinson’s real name, why does Polanski get a free pass?

Zack Polanski was born David Paulden on 2 November 1982[1] in Salford, Greater Manchester,[2] where he also grew up.[3] His Jewish ancestors had moved to the UK from Poland to escape the occupation by Nazi Germany,[4] but originated from Latvia which they fled to escape pogroms (initially to Ukraine, then to Poland)[5] in the early twentieth century. The family adopted the surname of Paulden hoping to evade antisemitism.[6][7] His parents divorced when he was young.[2] At age 18, he changed his name, restoring his familial name of Polanski, later saying it was important for him to take pride in his identity.[6] He also changed his first name, selecting Zack in homage to the Jewish character of the same name from the novel Goodnight Mister Tom, and to differentiate himself from his stepfather, also named David.[7]

Stephen Christopher Yaxley-Lennon[9][10][11] was born in Luton on 27 November 1982.[12] According to him in 2013, he was born Stephen Yaxley in London, and later adopted by his stepfather, Thomas Lennon.[13][14] He attended Putteridge High School.[15]

Robinson had an Irish mother and an English father. His mother worked at a bakery and at Vauxhall's car plant in Luton.[16] After leaving school he applied to study aircraft engineering at Luton Airport: "I got an apprenticeship 600 people applied for, and they took four people on". He qualified in 2003 after five years of study, but lost his job when he was convicted of assaulting an off-duty police officer in a drunken argument[16] for which he served a 12-month prison sentence.[17]

The Tommy Robinson from whom Yaxley took his name was a prominent member of the Luton Town MIGs, a football hooligan crew which follows Luton Town.[18] The pseudonym successfully hid his identity and criminal history until the connection was uncovered in July 2010 by Searchlight magazine.[19][20] He has also used the names Andrew McMaster, Paul Harris,[21] Wayne King,[22][23] and Stephen Lennon.[21]
