This started off with an email to Spark Arena, who did not reply. As such I will rephrase this in petition form. This is a call for Spark to cancel the event that Jordan Peterson will be hosting.

Spark Arena is hosting a transphobic, fascist, misogynistic, pseudo-intellectual hack called Jordan Peterson. Platforming him is harmful, and I am highly disappointed Spark did not vet their guest. 

Despite my attendance at a number of events hosted at Spark Arena, and prior when it was Vector, if this event goes ahead I will not be attending any further events and I will be encouraging my community, friends and family to do the same. 

First off, Peterson is someone who associates and is friends with members of an organisation that the NZ Government has deemed a terrorist group. 

Here's the evidence for the rest of the claims made:

1. Dr Peterson is Transphobic.

Dr Jordan Peterson recently tweeted "Remember when pride was a sin? And Ellen Page just had her breasts removed by a criminal physician."  Not only is this deadnaming Elliot Page, a man, which is a practice which has widely been criticised, he doubled down on this by saying "I would've left her [Page is a man] alone if she hadn't been parading her new abs in a fashion magazine". Peterson's implication here is that trans people are to be hidden away out of sight, not allowed to be on a fashion magazine simply because of who they are.

He then released a 15 minute video where he continued to misgender and deadname Elliot Page. Additionally, calling the doctor a criminal is an incitement to violence as the doctor committed absolutely no crime. By invoking this speech Peterson justifies retaliatory action such as harassment and abuse to the doctor.

Peterson became famous for actively fighting against the right for trans people to be called their correct pronoun - http://archive.is/3n8KK

It was neither a radically new law as Peterson suggested, nor did it criminalise misgendering someone. Here is the full text of the bill along with a letter from the head of the Canadian Bar Association.

So far, Peterson’s claims have turned out to be factually incorrect, in a very basic sense, when tested against the actual text, context, intent, and praxis of two thirds of the relevant sections of the Canadian Criminal Code. - https://archive.ph/mEuGg

2. Dr Peterson is a fascistic racist.
Peterson often refers to something called "cultural marxism". This is a play on something Hitler's Nazis made up in the 30s they called "cultural bolshevism" - the bolsheviks were marxists. This is an anti-Semitic, red-baiting conspiracy. Peterson calls gay marriage cultural Marxism (https://www.youtube.com/watch?v=4jef2C4T1_A). This is a dogwhistle to white supremacists and neo-Nazis. White Nationalists explicitly encourage people to use "Cultural Marxism" instead of "The Jewish Question" when attempting to radicalise others.

Posters note that the “Jewish Question” was often the hardest pill for them to swallow on their journey to the 504um, and that it is an obstacle to converting others: “I have found that most normies cant handle hearing the word jew more than a few times before they get uncomfortable and want it to stop,” one wrote. One recommended that the “simplest path to pro-white views” was “Cultural Marxism à Race à JQ.”  - Southern Poverty Law Center.

Peterson assigns readings from white supremacist Linda Gottfredson to his psych class (and not to analyze critically, but as "science").

Here is Peterson with the Proud Boys, a group the NZ Government has deemed a terrorist organisation, and a pepe flag, a white supremacist symbol - https://twitter.com/jordanbpeterson/status/957258128264871937  

He frequently invokes Western Civilisation and Western Identity as things that need to be protected, common neo-nazi dogwhistles too.

Peterson lends his support to "scientific racism" on IQ differences between races on white supremacist Stefan Molyneaux's channel, including talking about Murray's The Bell Curve as if it is valid, and not what it is which is sourced in neo-Nazi studies and a white supremacist eugenics journal. 

Here Peterson muses openly about what to do with low IQ people, eerily calling back to Aktion T4, the Nazi program of "involuntary euthanasia" (aka murder) of psychiatric patients, where the gas chamber was invented and where 300,000 patients (including children) were murdered. Again since many of his fans are neo-Nazis, this is also a dogwhistle.

White supremacist and Alt Right.com founder Richard Spencer, who argues often for a white ethnostate, is a big fan of Peterson’s work:
“Professor Peterson, I respect your work. And we share a lot of common ground and philosophical starting points.”

Peterson is also a big fan of right-wing troll Milo Yiannopoulos, praising him for "telling the truth", when in fact Yiannopoulos regularly lies, for instance on "Politically Correct with Bill Maher" where he made up false statistics about trans people committing sex crimes (in truth trans people are far more likely to be victims of sex crimes).

 

3. Dr Peterson is misogynistic.
In an interview, Peterson implied that men and women can't work together, and that women who wear makeup are hypocrites for complaining about sexual harassment. He later confirmed this when the interviewer clarified.

He complains about not being allowed to hit women if they're "crazy". - https://thevarsity.ca/2017/10/08/jordan-peterson-i-dont-think-that-men-can-control-crazy-women/ and https://www.youtube.com/watch?v=dL3Hrwg3A3w
He has been accused 3 times of sexual harrassment, and only 1/4 of women who have been sexually harrassed at work come forward, so there may be more. 
He believes men are "order" and women are "chaos". 

4. Dr Peterson is a pseudo-intellectual hack.
Peterson has a tenuous relationship with facts generally. Here Peterson psychoanalyzes Hitler, getting many facts wrong about WWII. Here Peterson claims Nazism was "an atheist doctrine", which is untrue.  Here is the Nazi Party Platform's position from 1920:
The Party as such stands for positive Christianity, without associating itself with any particular denomination. It fights against the Jewish-materialistic spirit within and around us, and is convinced that a permanent revival of our nation can be achieved only from within, on the basis of: Public Interest before Private Interest.
And here is evidence that the Nazis were no friends to atheists. Peterson thinks twin snake iconography means that ancient people knew about DNA, a bizarre idea, since ancient people didn't even know about cells.

Here is a document I have previously laid out in which I break down one of Jordan Peterson's lectures, with transcriptions. His lack of knowledge on the topic he's lecturing on is astounding, he makes things up entirely to suit a narrative, he lies, and he peddles pseudoscience and demagoguery.

5. Dr Peterson supports aggression towards children.
In 12 Rules for Life, Peterson openly fantasizes about committing child abuse against a 2-year-old, and justifies his sadistic fantasy as being beneficial:

I remember taking my daughter to the playground once when she was about two. She was playing on the monkey bars, hanging in mid-air. A particularly provocative little monster of about the same age was standing above her on the same bar she was gripping. I watched him move towards her. Our eyes locked. He slowly and deliberately stepped on her hands, with increasing force, over and over, as he stared me down. He knew exactly what he was doing. Up yours, Daddy-O — that was his philosophy. He had already concluded that adults were contemptible, and that he could safely defy them. (Too bad, then, that he was destined to become one.) That was the hopeless future his parents had saddled him with. To his great and salutary shock, I picked him bodily off the playground structure, and threw him thirty feet down the field.
No, I didn’t. I just took my daughter somewhere else. But it would have been better for him if I had.

This is in print. And this is with the knowledge from 50 years of research that corporal punishment increases child misbehavior, aggression, defiance, and other negative outcomes, something Professor Peterson, Clinical Psychologist, ought to know.

6. Dr Peterson is a climate denier.
