Obama follows my advice; and what is a lie?

Last blog I observed that Obama should come out and articulate three main goals for health care reform. He wisely did just that in his speech last week. Now there is something to debate.
But this blog is about the application of sound reasoning and logic to public discourse. During Obama's speech a member of the audience shouted out "You lie!" when Obama said that the reform bill will not pay for illegal immigrants.
This brings us to the discussion of what is a lie during public discourse.
All politicians, and salesmen, and ceo's and managers and pretty much all public spokespeople put "spin" on whatever they are saying. They try to word things in a way such that concerns are masked and positive attributes accentuated. These are not considered lies. Often such speeches are full of opinions and misleading facts. Often the opinions are summaries from reputable organizations, they are still opinions, although people generally considered experts might agree with them.
Other experts might disagree with those opinions, that doesn't make them lies. Other facts might provide evidence against the conclusions, that doesn't make having those conclusions lies. In the case of healthcare reform not paying for illegal aliens, we need to analyze what aspects of the reform might cause someone to think that it does; what aspect of the bill does the disrespectful member of congress feel contradicts the claim that illegals will not be paid for? What do people mean when they voice concerns about illegal aliens having their health care provided by Americans? What are they worried about?
In private conversations I have classified the health care "issue" as an economic issue, for which I was chastised. I suppose it was considered "insensitive" or too "dispassionate" to consider the issue an economic one. But it has been proven to be truly economic. The controversy is not about finding a cure for AIDS or cancer, streamlining FDA approval for various therapies, or breakthroughs in diet and exercise understanding, the controversy is clearly about who pays for all these things, and how much do we pay. It goes to the heart of what is the proper role of the federal government in society. Many people think of course the federal government, i.e. the American population as a whole, should provide health care for everyone regardless of economic circumstance. Many people think that each person needs to decide for himself what course he follows to provide health care for himself and how far his responsibility goes toward supporting others. This is what the debate is about. At some point a particular opinion will be put into law, but it will still be just an opinion. The only liars are the ones who refuse to admit this.
