Honestly…no.
Well, I read back through the thread. If country other then the United States, Canada, and Iraq is being invoked in this discussion… news to me.
If I may, what I’ve figured out is that a blunt direct statement with some minor element of support (provided one does not look too closely) is often accepted as fact, and then used to support numerous beliefs based on that fact.
Blunt direct statement: Iraq had WMDs and an aggressive program of research and production, making them a serious and increasing threat.
Supporting evidence: Iraq had indeed used chemical weapons against a civilian population (namely, the Kurds) in 1988.
A great deal of emotional investment went into the issue of invading Iraq and ending this claimed threat, and I can understand it. The U.S. had been recently attacked and a lot of its population was happy to strike back at somebody, helped along by a president with an agenda and some vague claims about yellowcake and “Chemical Ali” and such. Someone with such an emotional investment (i.e. a firm belief that the invasion was justified) is told that that original statement was untrue or grossly exaggerated, I can understand resistance.
The notion that Montreal “safely” hosted “the 9/11 perps” is also understandable as the basis for emotional investment. I don’t know what emotional investment (if any) Elvis has in this, but I can speculate: the U.S. stands alone, and even countries claiming to be close allies are working (wittingly or unwittingly) against U.S. interests; it’s inconceivable that terrorists plotting a major attack in the U.S. could, until the day of the attack, move freely within the U.S.
For this specific issue, the idea that socialized medicine would deprive citizens of control of their own health is a statement, comparable to “Iraq has WMDs” or “the 9/11 perps were safely based in Montreal” in that they should be fairly easy to prove or disprove, if one wants to invest the effort. Instead, these statements are not being explored by the people who’ve built whole attitudes based on them, and they have no incentive to do so. After all, what can they possibly gain?
So, yes, the Republicans can lie. The statements they make are eagerly embraced by people who are already inclined to dislike governments. The Republicans get away with it because they can, because the people who believe the lies resist being told otherwise, and the person making the challenge isn’t to argued with, but ridiculed and marginalized as much as possible. Hence teabaggers who chant slogans, and Elvis calling me “junior”. It’s not defending the lie; it simply seeks to avoid examination of the lie.
