The most cherished myth among pretty much any political group is that there’s media bias against the group. Almost as common, though, is the idea that there’s a conspiracy — that sinister people are plotting together to make your group look bad.
I know it’s hard to believe this, but your conspiracy theories just aren’t true. The world doesn’t revolve around you and your group — and there isn’t some plot to make you look bad. (In fact, every group does a good enough job of looking bad that nobody needs to help.)
Conservatives complain about liberal bias. Liberals complain about conservative bias. Libertarians complain that pretty much everybody hates them. I’m not sure what socialists complain about these days, but it’s probably about the anti-Marxist bias all around them.
(For the language purists among us, let me point out that I’m using “conservative” and “liberal” in their generally accepted mainstream definitions here.)
