It's late, so I don't have the best examples, but I have a vague impression that there has been an increase of single-dimension, with-us-or-against-us identity politics. Perhaps I'm mistaking noisy for large. Even still, many of these groups do have legitimate claims...

Reflecting a bit, I suppose one main reason I posted was that I didn't like the implication that the mainstream left has become enlightened past the point of ideology. But perhaps that point is too much of a distraction in this conversation. Meh.

Btw, not that it should matter, but I lean left and voted for both Obama and Hillary.
