Tribalist here in the sense of those who are complicit with In-Group/Out-Group dynamics [1]. Knowing that Assange is some sort of anarchist helps [2]. Such language is common within a certain political perspective that includes anarchism; these 'horizontalist' 'global citizens' envision a utopia and as they work towards it, in addition to opposing establishment climbers especially, they often look down on and view 'identity politics' or 'lifestyle politics' (and the use of ideological labels and in-group signaling all together) as base and beneath them [3]. And yes, they often practice the same things they critique and theoretically oppose.

WikiLeaks account looks up the profile pictures of many of its critics and notices that they all wear black-rim glasses, which strikes WikiLeaks admin as bizarre?
The author, Emma Ellis, has no comprehension of the tweet in question. Understanding the background could have prevented this:
1. Neo-Nazis begin to point out to their supporters that the people they are discussing are Jews (or "Jew aiders and abettors" [sic]) by placing three brackets around their name. The subjects are often unaware and their account usernames (obviously) do not display brackets.
2. In reaction to this, numerous camps (social justice activists, evangelical Christians, civil society workers, journalists, etc.) both Jewish and non-Jewish alike begin to place three brackets around their display name to draw attention to the practice and to express solidarity with those who are being discussed in brackets, a practice sometimes revered in Western culture [1][2][3][4].
3. A subset of these self-labelled, self-bracketed individuals criticize WikiLeaks.
4. The WikiLeaks account notices that many of their critics are self-bracketed individuals expressing solidarity and wonders what type of people do this, as one might question the individuals who change their profile pictures to have a flag overlay for the tragedy du jour, and if said people are doing so for their own interest.
