Drinking the Kool-Aid: a new idiom

[Julia Van Nutt]

The term "Drinking the Kool-Aid," has been around for some time. It
dates back to the Jim Jones tragedy when all of his followers, or
true believers, voluntarily drank what they knew to be poison laced
Kool-Aid. Since then, I have heard the term used to describe
unquestioning obedience and belief, often in contradiction to
overwhelming logic.
