No, what is happening is not the definition of insanity, at all.
It's evidence that some very long-term CureZoners that have always lived together peacefully (and shared information respectfully...even when they adamantly disagreed with each other) - are very, VERY concerned that someone threatening lawsuits against the site/Webmasters and other forum posters desperately needs to be addressed.
It's called loyalty, integrity, honesty, a great sacrifice of personal time, and grave concern for every posters ability to share with others freely (no matter what their belief).
