None in particular. I was talking about "primary sources" as a category. See also what I wrote here:

It was a meta point. Sorry if I gave you the impression that I was weighing in on the particulars of jmyeet's essay. Rather, it was a high-level point that if you know a ton of little facts but you're only seeing half of the story, then you need to improve and broaden out your intake.

I would have the same opinion of a poster who was so one-sidedly pro-America and anti-China.
