um. I don't like disagreeing with you, but...
From my own observations, it seems to me that, while it may not be quite as bad as the Rand study indicates, it is far more prevalent than "a small percentage that wears tin foil"
You would not believe some of the crazy ideas I have encountered from patients while working in a medical practice. While simple ignorance and profound stupidity are essentially uniformly represented across all demographics, the truly loopy ideas regarding health and medicine are definitely much more heavily subscribed to among blacks.
And do you think the Democratic party helps spawn these crazy ideas so as to keep the black population from furthering their self reliance?
