As a healthcare professional with an M.Sc. in human growth and development, I am a South Park conservative, more or less. Not having read the book, I cannot be sure. I am one of those exposed to Ayn Rand via the Fountainhead around the age of 16 years and it has stuck with me for decades. I am not a Libertarian, Anarcho-Capitalist or Randian - although many would lump me with the former. I await the Tea Party revolution with breathless anticipation.
I believe in serious political discussion but with optimism - humans haven't got where they are by being completely stupid and incompetent - at least not consistently or irretrievably. Hey Bill Murray got it right eventually in Groundhog Day.
Conservatives should not come off as being so dour and depressing as they often are - especially lately. Liberals are usually worse. There is much cause for concern, but for optimism as well. Ronald Regean was above all an optimist who embraced the future and the possibilities for greatness there.
I share his excitement about the future - cheers!
