> every other one is liberal
I don't agree.
First, there are plenty of smaller conservative ideological publications (two were listed in the original comment, plus endless more: RedState, Daily Caller, Breitbart, etc.). Almost all talk- radio, as I mentioned, is conservative.
Also I said in another comment, there is plenty of apolitical journalism.
(!conservative) != (liberal)
The ideologues adopt a Manichean, binary view of the world: With us or against us. They say everyone is ideological and anyone who doesn't agree with them must be in the 'other' camp. They seek ideological conflict, to justify their beliefs and behavior. But the world is more complex than that and everyone is not ideological (most are not).
There are leftist ideologues, and they say the NY Times is conservative and there is no difference between the parties (as incredible as that sounds). Either you share their ideology, or you are in the 'other' camp.
The right-wing ideologues are the same: They define any journalism as not ideologically conservative as liberal. (They also call themselves outsiders when the control the 2/3 of the states and both houses of Congress). But it's not the case.
