A colleague asked me the other day if I felt there is a blacklist in literary s-f against non-PC writers.
I replied I don't know, there's no way to tell for sure; that's the nature of a blacklist - it's a conspiracy.
I will say that before 2015, when I was a double Sad Puppy Hugo nominee, my rejections almost always included invitations to submit to that market again.
Now, that is very uncommon, and in fact almost all my rejections now end with "best of luck" or "good luck with your writing" - and no encouragement to submit again.
Of course, there is always the possibility my writing skills have declined in the past couple of years - but that would run counter to experience.
Being a glorified hobbyist in the field, it's not that big a deal to me. I really write for my own personal pleasure and the enjoyment of my fans. If I tried to make a living as a short story writer, I'd be as broke as Howard Waldrop.
Still, I'm left scratching my head, because the verbiage of the rejections I receive has definitely shifted, and wording of the various "good luck in your writing" observations is very consistent.
