It's especially frustrating watching congressional hearings. Since both "sides" are aware that the cameras are rolling and that they are there to score points/create soundbites (rather than actually learn from each other--god forbid) it's just both sides talking past each other and not doing the analytical work of a good conversation.
Even when I'm on one side of the argument, it's just as frustrating to hear my own side just move on to their next pre-written question/response instead of engaging with the underlying issues. I want substantive debate and discussion and possibly consensus, but that's sadly not the reality in most cases of import.
