Keith Burgess-Jackson attempts to explain liberal anger from his converative viewpoint. His specific targets are Brian Leiter and Henry Farrell, but he lumps all liberals in with them:

Deep down, liberals know that they have lost the battle for the hearts and minds of the American people. They control the media, Hollywood, the courts, and academia, but little else. They sense that all is lost—that what they perceive as rollbacks will be permanent. ... What we are seeing is a grown-up tantrum.

So how do you explain all the angry conservatives, Keith?

My suggestion to everyone out there, left and right, is to quit the armchair psychoanalysis of the political opposition. It’s a load of patronizing bullshit when liberals do it, and it’s a load of patronizing bullshit when conservatives do it.
