Though I think that the folks who fit the “liberal elite” definition are much fewer than many conservatives would like to think, I do agree that there are folks filled with self-righteous indignation that is neither warranted nor earned.
But I would of course say the same is true for the other side. There are conservative elitists who are sure they are so much smarter than those stupid liberals, but I don’t really think they represent the majority of conservatives.
