Sneering at people who make public gestures of opposition to anti-Semitic tropes as "establishment climbers" sounds like pandering to a particular form of base racism to me, assuming you do so intentionally. I'll concede that it's possible that Assange or whoever tweeted that was unaware of what the parantheses symbolised in a way that someone tweeting "Tribalist symbols for establishment climbing? Most of our critics have pink triangles in their avatar" or worse "Tribalist symbols for establishment climbing? Most of the our critics have yellow stars in their avatar" really couldn't claim (I bet most people not involved with political Twitter are clueless about the parantheses' meaning). But conflating a Jewish symbol with the age old conspiracy theory that the "establishment" is run by people that suck up to Jewish interests by accident is certainly unfortunate....

And it gets even harder to defend the @Wikileaks Twitter account from pandering to anti-Semitism after looking at several of the other tweets unearthed by this search... https://twitter.com/search?q=from%3Awikileaks%20jewish&src=t...
