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

Alternatively, one is a racist, right wing thug with a criminal record and the other is a left wing charlatan, that has history of scamming women into believing he can hypnotise them to grow bigger breasts, retracted his claims and then double downed on them. Not a lot to choose between 'em really.

I think that’s very unfair.

But each to their own!

I assumed it was just because one of them is using his own historical family name, and the other is using multiple pseudonyms?

Not a lot to choose between 'em really

In terms of integrity, little.

Because one is a vile, racist thuggish criminal and the other isn't?

David Paulson aka Zak Polanski has just made a statement about antisemitism:

I am concerned about the rise in antisemitism and we know Jewish communities are saying they feel unsafe. There is a conversation to be had over whether it's a perception that they feel unsafe or whether they are actually unsafe.'

Yeah, he's right; firebombing synagogues, shooting Jews as they attend their place of worship, setting fire to the outside of their synagogues..... feeling unsafe in those circumstances is just perception. T**t.

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]

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]
