The question you should be asking yourself, Corinthian, is:
Why are the Quackbusters engaged in attacking free speech?
What kind of person does that?
Being that kind of person is a requirement for being a Quackbuster.
That realization, by itself, should give one pause when considering the validity of the Quackbusters and their position.
You know, like how you instantly reject an argument from a Creationist against Evolutionary theory, no matter how well reasoned or well founded, by virtue of the fact that Creationists are a breed apart and have their own agenda, etc....
