This man is extremely dangerous not only for America, but for the entire world. Obama might not be any good, but Romney will destroy the American dream, and several other countries along with it.
This is why American politics is in such a sorry state.
I watched the Stewart / O'Reilly debate yesterday, and, surprisingly, came out of it with a bit more respect for BillO than I had before. They both made some bullshit claims, and some good things to say, though Stewart was by far the more compelling of the two despite being frequently childish (as I expected, just as I expected BillO to be frequently churlish). In Stewart's closing remarks, he said that the biggest problem in American politics is that the people backing both teams are so caught up in this idea that if The Other Guy gets in, it's going to be the end of the world. It's not.
Personally, I don't go in for either of the major parties, and I think both of them are going to foster the slow decline of America. I don't know if that can in practice be helped any, but this incredible polarization, the idea that the opposition is not only to be disagreed with but reviled as the worst possible humans who will destroy everything, is extremely unhelpful and flat-out wrong. Until we can return to a civilized discourse, where policy can be expressed as better and worse instead of better and Oh My God What Are These So-Called People Thinking, there is no way to really hash out anything that is going to work as best it can.
I'm not absolving myself from guilt in the matter, either--as a person who is dissatisfied with the whole system I've definitely fallen prey to the urge to claim that we're on a brink of some kind, and more than that I've fallen prey to believing it. Yet I can't help but wonder if airing those concerns is at all helpful: in essence, you are not only preaching to the choir but alienating every thinking individual who might respond better to a more reasoned analysis of the situation.
I don't have all or any of the answers, but demonizing the opposition isn't going to do anything except for strengthening their belief that you are also to be demonized instead of engaged with.
