Having finally gotten through the DDOS-filter, I see from her account of the situation that my hopes were not enough to change reality. There is a bit of "here's an opportunity to make my point," that leverages a minor incident to reinforce her larger message about inequality.
The thing I took from the photo (which I agree was a bit much) was that this woman of color was surrounded by a bunch of white dudes with corrective lenses. There was a man of color farther back, but diversity was not on display.
One of the guys even had a weak smile as if he was thinking,"ohmanagirlislookingatmeandtakingmypictureimayloveher." But I'm assuming he's straight, which is my own lens on the moment.
I hope that her goal was to portray that lack of diversity rather than to shame the two participants in the conversation.
