That statement is wonderfully disingenuous. Here's what happened:
Douglas Fox, a pimp, joins Amnesty International in 2008 and immediately starts agitating for full decriminalisation.
He joins the 2008 Amnesty UK AGM and angrily confronts feminist groups who are also there campaigning for a Nordic Model approach.
He writes and submits a motion arguing that it is a human rights violation for pimps and punters to be criminalised, calling for the buying and selling of sexual services to be decriminalised, and relabels pimps as sex workers. In short, he proposes a motion that is designed to protect prostitution not prostitutes.
The motion is rejected with about a third of delegates in favour.
Douglas Fox leaves Amnesty in 2009, but continues to lobby for full decriminalisation and encourages other pimps to join Amnesty to lobby for full decriminalisation.
There is plenty of evidence that key members of so-called sex workers organisations are pimps, including the aforementioned Alejandra Gill, Vice President of NSWP, the Global Network of Sex Work Projects.
In 2016, Amnesty publishes a report called WHAT I'M DOING IS NOT A CRIME. THE HUMAN COST OF CRIMINALIZING SEX WORK IN THE CITY OF BUENOS AIRES, ARGENTINA and includes the following quote on page 28:
^According to sex workers interviewed by Amnesty International, the psychologists accompanying officers on raids can be forceful in their questioning and often tell sex workers that they are victims of sexual
exploitation, even when sex workers are adamant that is not the case.^
“The psychologists tell you to say you’re a victim of sexual exploitation. Workers are frightened by the whole situation so of course they say they’re victims. They also tell you to say that and that if you do, they won’t call your family. They take pictures of you.”
Amnesty International interview with Claudia Brizuela, a street-based sex worker and head of AMMAR Capital, 24 September 2014
Claudia Brizuela was arrested and charged with sex trafficking in 2015 in a harrowing case involving over 30 women described as extremely vulnerable in local press reports. Another head of AMMAR, another one of those so-called "sex worker" organisations campaigning for full decriminalisation, was also charged with sex trafficking in a different incident.
The list of key people involved with the "sex worker" organisations advising Amnesty on its prostitution policy who actually turned out to be pimps makes for an interesting read. There's a non-exhaustive list at the bottom of this page here: logosjournal.com/2016/farley-2/
Interesting are also the testimonies of survivors of prostitution who dared (and continue to dare) argue against Amnesty's policy, often ignored, sometimes even bullied into silence by Amnesty International or local Amnesty branches when trying to speak out against its prostitution policy.
You'll find them in this Amnesty Dossier written by Normac, an Australian group campagning for the Nordic Model approach.
Anyway, back to Douglas Fox, co-founder of the International Sex Workers Union and NSWP. In 2009, the year Douglas Fox left Amnesty International, the NSWP (which he continues to use to lobby for full decriminalisation) is appointed co-chair of UNAIDS and advises that organisation on their prostitution policy. In turn, both the NSWP and UNAIDS are credited with advising Amnesty International on their new prostitution policy.
Douglas Fox may have had his motion rejected at the 2008 Amnesty UK AGM, but six years later his demands and statements are included in the leaked 2014 policy proposal. Including the later deleted and rather astonishing claim that criminalising pimps and punters amounts to a human rights violation.
In the end, Amnesty International follows Douglas Fox's demands and adopts a prostitution policy that protects prostitution but not prostitutes.
I honestly don't even know why Amnesty International keeps denying that its policy was influenced by pimps and punters. If looking at all the so-called sex worker organisations run by pimps and punters who advised Amnesty isn't enough, all you have to do is look at the policy itself. It does state after all that it's ok with states criminalising the selling of sex while adamantly demanding that pimps and punters should not ever be criminalised.
