I mostly read (hard) sci-fi written by straight white dudes, so the tweet on the screenshot made me feel a bit defensive. In the replies and qrts people are patting themselves on the back for reading marginalized fantasy writers exclusively and this "consumption as activism" seems rad-libby to me, but maybe I'm wrong.
Ah, fuck that then. I wish the dumb libs could actually understand the difference between attacks from the left and attacks from the right.
