I've been watching the discussion of millennial citizenship on the HuffPost. It's a spirited exchange. Perhaps it's worth taking a step back and re-examining what we mean when we talk about political engagement; at the core, I'd submit, are principles that apply regardless of age or demographic. It's the ability to engage in critical thought that makes us "citizens," rather than mere "consumers" or "taxpayers." It's the ability to follow a line of reasoning, to view an argument analytically, to evaluate the evidence on which it's based and determine whether it makes sense.
