I've been following the thread for days, and thinking, rather than replying.
I have no trouble understanding that my white skin protects me from racism, and that this isn't the case for many women around the globe. Racism is unjust, and a double burden on women who are not white.
I think where there is a disconnect is the assumption that this white privilege automatically translates into significant social, economic and institutional capital for white women as a whole.
Personally, I have very little economic or social capital, despite being white. I have my one vote, I occasionally have spare cash to donate and I have a small circle of family and friends, none of whom deny their white privilege (for those who are white - my immediate family isn't).
So these calls to perform allyship leave me somewhat bemused. I already use the very limited amounts of capital I have in pro social (including anti racist) ways, and that's about all I can do.
It's as if there's an unspoken need in the conversation, and I'm not sure what it is, or how to meet it.
I've audited my own life, and I'm satisfied that I'm doing what I can on issues of race that pertain to my own country.
Am I an ally? By the standards on this thread, possibly not. Am I truly doing what I can within a very small sphere of influence? Yes.
It may not be enough to assauge the pain of racism. That's sad, but it's also realistic.
