I don't see it so much as a point oriented article, but more the sharing of impressions from an event. I don't want a theatre critic in long-form to have a point, more to give what the impression is.

With that said, I don't think that the idea of White Appreciation Day is the problem. I see it as that it was stated that every american is welcomed, every one is celebrated. But at the same time everything that doesn't fit the mould is under threat. The bathrooms are a very easy symbol for that. Meat and BBQ are masculine (There is the trope of "Man orders steak, woman orders salad") and so all the outside of the restaurant is geared in the masculine. The women's bathroom is a feminine space to the extreme. The feeling is that anything that doesn't fall into the easy boxes is just excluded. Add to that "everybody has a gun" and suddenly the fear becomes close to panic. And as for the books mentioned, I see it less white guilt and more to remember that there are others. That the ethos of all inclusivity doesn't really work.

This are my impressions of reading. Nothing states that they are right. They are fueled by own experiences as a non-white, non-citizen US resident. I might be reading a bit too much into this.
