The first part to being able to solve a problem is to even recognize that it's a problem. And particularly when it comes to privilege, which tend to be highly subconscious and a lot of "you don't know what you don't know" - identifying that it's important to recognize privilege (because white women are also oppressed and so they may tend to focus on that part), to encourage open discussions such as this one, asking the questions about how we can do better - those are all incredibly meaningful and important steps toward being able to tackle a deeply entrenched and complex issue. Imagining that any one person has the 1.2.3 answers to something like that in a 5 minute story is not exactly a reasonable or even a rational request. In fact, it seems like a backhanded way of dismissing her and condescending to her.
One of the main things about this piece was how much of this happens subconsciously even to women who have good intentions, and who work in fields where they are trying to help marginalized people. If you've got some quick and easy answer for how to "fix" what's in people's subconscious due to their lifelong indoctrination into a racist patriarchal culture, how about you share those instead of going after someone who is actually engaging in a valuable conversation.
