Commentator James May over at Brad Torgersen's blog made this observation;
The problem to me is pretty clear: the core community used to act as custodians of their art. They promoted and taught art appreciation and acted as curators. The Hugo Winners and SF Hall of Fame anthologies operated much like a museum. People said “This is what we think is good” and they made a case for it. They understood the evolution of their genre. Now Jack Vance dies and they say “Who was that?” They’ve never heard of Lord Dunsany...
...However you felt about it, comics in the ’50s and movies in the ’60s were critiqued from a standpoint of a shared American cultural failing. Today supremacist feminists in SFF and also like Anita Sarkeesian and Brianna Wu are critiquing whites and men instead. You just can’t do that to art. The next Vance or Bradbury can’t emerge from that sort of system. Not only are they not being cultivated they’re being actively discriminated against. SJWs openly sneer at the idea of a meritocracy, a common thing for failure. Look for failure, cultivate it, and that’s what you get.
