Nice analogy, but it fails miserably.
The whole job of a political journalist is to find out accurate facts about politics. When they notice that (let's be fair) 95% of conservative talking points are crap, then not only are they going to reject the talking points, they're going to think that if there was any merit at all to conservatism they'd have some talking points that weren't crap.
This would be true if those political journalists were unbiased. Clearly they are not. 80% or more of them vote Democrat and are well left of center. The mainstream media culture as a whole is left of center.
Perhaps those of you who also are left of center assume that your's is the only correct position, and that you are mainstream. This is not accurate.
Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.
