I don't think gell-mann amnesia applies here. At least, it doesn't apply to me in particular. I'm moderately well informed about the topics I've posted, and not particularly well informed about U.S. politics. If anything, you've got it backwards (at least in my specific case) -- I'm reading the topics I don't know very well with increased skepticism, and am more trusting when I see that topics I'm better versed in are presented well.

I would agree in general. A paper that was consistently wrong about sports might still be trustworthy about science.
But almost every story touches on US politics, so misleading the public about US politics casts doubt on all of the stories. They're probably still trustworthy on sports and celebrity gossip, but politics influences science, medicine, business, economics, international news, etc, so their bias in politics is likely to infect all those other topics.
