So this had happened enough times for me to subtweet:
Performative anxiety about diversity which *ignores the actual diversity in the room* is crappy and hurtful and actually pretty racist.
Examples:

A white ALP hack listening to a Greens speech by a candidate of colour and tweeting about the lack of racial diversity in the Greens
an activist action organised by 2 ppl - one of them a queer WOC - is described as “the epitome of white privilege” by a white critic

a non-black POC expressing concern about the lack of black leadership *in a meeting chaired by a black person*
a white woman in a very small reading group (of four white women and one woman of colour) espouses her dissatisfaction that “we’re all just white women”

It’s really good to think about the racial makeup of your groups, actions and events! It is not at all good to erase the racial identity of your comrades, friends and collaborators. Doing so suggests you care more about scoring political points or virtue signalling than you do

about, you know, the racialised people in the room. Don’t do it.
