See, this is a place where the US is different from Europe. Because over here (at least in the bit of Europe I'm in), being "somewhere to the right of socialism" isn't thought of as the kind of crazy extremism that ipso facto makes someone dangerously biased and axe-grindy.

Now, of course politics is what it is, and affiliation with even the most moderate and reasonable political position can make otherwise sensible people completely blind to what's obvious to others. So the fact that being almost (but not quite) a socialist looks to me like a perfectly normal and sensible position is perfectly compatible with Shalizi being made nuts by it. But to me "he's somewhere to the left of Barack Obama" doesn't look on its own like something that makes someone a biased source and explains what their problem is.
