On 30 September a tweet was made from the official Twitter account of the Free Gaza Movement (@freegazaorg) which stated “Zionists Ran the Holocaust and the Concentration Camps.”

The tweet linked to a video of an anti-Jewish diatribe by notorious anti-Semite and conspiracy theorist Eustace Mullins.

The tweet’s contents originated as a posting by Free Gaza Movement’s Greta Berlin on her personal Facebook page. It was posted automatically from Facebook to Twitter. Following considerable uproar over this tweet, the Free Gaza Movement posted a statement on its website on 4 October that included the following explanation:

A TWEET from the Free Gaza TWITTER account was posted several days ago that had a link to a lecture titled, “Zionists Ran the Holocaust and the Concentration Camps.” This TWEET did not come from Free Gaza, and does not represent FG’s position in any way whatsoever; in fact we condemn its content. It came from Greta’s private Facebook page and was shared with a group of people who were discussing propaganda and racism, and this link was an example of the terrible propaganda that could be spewed on websites. For some reason, Facebook connected our Free Gaza account to her personal Facebook account, and the link was posted.

This statement did not calm the growing controversy. In order to dispel any doubts, many people, including me, asked Berlin to publish screenshots of the discussion from Facebook to show the context in which the video was posted. Berlin, who controls the @freegazaorg Twitter account, refused.

This evening I had an opportunity to spend several hours with full access to a private Facebook group of which Berlin is an administrator, and where the video was first posted by another administrator on 28 September with the comment “This will be a real thought provoker for some.”

When the video was posted on 28 September it was neither preceded nor followed by any interactions that would fit the description that it “was shared with a group of people who were discussing propaganda and racism, and this link was an example of the terrible propaganda that could be spewed on websites.” This context does not exist.

I have no doubt that other members of the Free Gaza Movement took Berlin’s explanation in good faith. Now is the moment for them to demand proper accountability.

As members of a broad and diverse Palestine solidarity movement, our loyalty to one another can only be based on trust and honesty.
