It's political but it's not capital-P political.

Politics is a sufficiently broad idea that virtually all the machinery of society would qualify, but what's being spoken about here is the kind of politics that has to do with propaganda and information control. And indeed, this is not that.

There are many different usages of the word. The one in legal theory that, for example, is used by courts to exclude cases of a "political" nature is of course different from the one used in academia or else all cases would be forbidden!
