I used to be a big Sci-Fi fan. Then, about 10 years or so ago, more and more Sci-Fi authors were coming out as gay and the characters in their novels were gay. Sci-Fi seemed to be a way to get gay literature under your radar and into your home, with the fantasy part acting as a sort of sugar coating. I don’t see my favorite authors putting out books any more, and I don’t enjoy the twisted stories coming out now.
Your post is correct—there are fewer and fewer new SF books worth your time.
The other “politically correct” infection of science fiction was having black scientists, entrepreneurs etc lead the way to the new future....
The pandering just got over the top...
