Yes, the critical theory is what I'm talking about, and I think that knowledge is definitely associated with the political "left". The issue I had is that the skepticism is almost always ignorant and dismissive. It's just impossibly frustrating to try to talk to someone who refuses to do any background reading but wants to tell you you're wrong about concepts that live in an academic and historical context.

As for the military, I guess that one is more debatable. I agree that the Bush-era "support the troops" jingoism isn't around much, but I used to see a lot posts where it's implicit. Things like hugely popular photos of special ops soldiers followed by adoring comments of how "badass" they are.
