I haven't read them, I haven't judged them.
I'm reporting to you and anyone else who read it that while in attendance at worldcons pre-sad puppies, there was active campaigning for books based on the identity of the author. Sad puppies did not occur in a vacuum. I'm in no way justifying any stuffing the vote or any other shenanigans.
I will say that the last 10 years of winners are certainly more obscure than any 10 years from 1960-2000. Individually an obscure book may be great. As a trend it seems unlikely.
I may be missing out on something from the last 10 years. But after 40+ years of reading, why am I not getting recommendations on anything in the last 10 years (again, except for Three Body Problem)? You dodged that question also. No recommendations from the last 10 years? Why is that?
I won't read something just because it's written by a woman or minority. -- me
I won't read something if it's written by a minority. -- not me
I won't read something just because it's written by a man. -- also me
I'll read something if it is recommended. -- I may judge the recommender if it is awful
I'll read something if the story sounds interesting. -- very little emphasis of this at worlcon
