Hmm, your read of the article is a bit harsher than mine. I don't think Wilson is particularly invested in the purity of hard science fiction, for example--his published fiction is all fantasy as far as I'm aware. And when I think of writers who were "extrapolating science of the new into a future situation and building a world from there that takes the science fiction as science fact," I don't think that's Delany at all.

I can't say there's definitely no sexism mixed into Wilson's critique. But I will say that as a queer man myself, I share his concern that there are so few queer men writing sff, and so much sff about queer men is written by women. Ownvoices is not a panacea (and "don't write people different from you" is a recipe for both artistic and political failure), but having a reasonable number of our own voices in the mix is important. I just wish Wilson had gone on to interrogate what's going on in publishing that has led to this situation. I wonder if it touched too closely on his own experiences, or if he feared it would read as a personal complaint.
