Lets say tomorrow a Republican announces that they have conclusive proof a terrorist group is about to attack the Sears Tower. Almost all of us here would go, "yeah, right", right? We've heard this one before. But what if they were right this time (and, when you think about it, it's not an implausible scenario)? We wouldn't believe them until smoke started to rise from the building, and even then some percentage of us would be talking MIHOP and LIHOP. Because we don't trust them already, we will doubt everything they say.
Well, Religious White (until recently) Republicans do not trust Democrats or liberals. They have gotten their news from Fox, which has been confirmed through commission or omission by their other news sources, and these news sources have told them not to trust Democrats or liberals of any stripe. Unless people were fortunate enough to have countervailing influences (such as active participation in politics prior to the propaganda exposure, or personal acquaintance with liberals and liberalism, or exposure to trustworthy alternative information sources) that kind of propaganda
works. Most people who haven't actually studied persuasion grossly underestimate its power and grossly overestimate human rationality, but I guarantee you, even we here have been subtly influenced by the propaganda barrage.
Democrats (and liberals in general) have until now not had a clue how to respond to the Republican propaganda machine. We've tried to act as if we had a functional democratic dialogue in place, and have continued to talk about issues. But we have not had such a dialogue in place since the rise of Atwater (Atwater is who
I learned these techniques from, myself). I don't know that we yet have a strategy in place to deal with propaganda. Overt propaganda such as the Republicans and Murdoch use (as opposed to ordinary rhetorical techniques)
isn't compatible with the democratic process, and it can't be countered with more of the same.
However that old friend of ours, reality, has a way of eventually biting those who ignore it in the ass (no pun intended, but since it just sort of "came out"

)
As a consequence Democrats and liberals have screamed to high heaven about things like torture, and these people have dismissed it with a "yeah, right". They don't necessarily
not care about these things, they just don't take news of them seriously, just as we don't not care about terrorism, we just don't believe the administration anymore.
But the Foley affair, while not so important in and of itself, opened a lot of eyes. The Republicans it turns out (not to my surprise as a former Republican, and not to the surprise of the vast majority of us here) are
not more moral than the rest of us. And if they aren't... then could the other things people say about them be true? Like say, lying about a war? Torture? Fiscal madness? Corruption?
Once someone's faith in something has been cracked, then the rest of the truth can trickle in (for some people) or pour in (for the earliest of the defectors, no doubt). It's that -- that the matter struck at the trust the Republican base placed in their leaders -- that makes it so serious an issue. If the breach can be worked, and the doubters shown the rest of the truth of the people they believed in, they will not go Republican again in our lifetimes. Every time a Republican opens his or her mouth, they'll go "yeah, right".
