MLK said it best: "the moderate who is more devoted to order than to justice, who prefers a negative peace which is the absence of tension to a positive peace which is the presence of justice"
And even now you have people that think showing up with clever signs around the downtown parks / public areas on the weekend when all the government offices are closed are somehow going to get their message across. It's not enough. It was never enough. It wasn't enough for Vietnam or Iraq. It's definitely not going to be enough now. Americans are going to have to choose to do some uncomfortable and maybe even risky things to demonstrate our disapproval.
Or we have to admit that for many of us, this is who we actually are as a country. It certainly is a good bit of the voting public. I don't think it's a mistake that in basically one generation we lied to the world about Iraq then elected a fascist twice. And at that point I don't think stern dissent is an effective or even morally correct course of action.
