Absolute and total bullshit, she goes on abut class all the time. Taken almost at random from Ambreen's blog:
"Have you ever felt dehumanised on the basis that you are not white and middle
class? As an ex Muslim working
class woman of colour with mental and physical disabilities and a queer identity, I have been made to feel subhuman on each of these accounts separately. I cannot reject the experiences of a white working
class woman but I can remind her that she does not face the risk of death for leaving her religion nor will she be questioned about whether she is a Muslim when she isn’t one, for the rest of her life. Some people don’t even ask if you are a Muslim, they just assume and snarl at you instead. Even white working
class women have white privilege."
