Conspiracy. "You're crazy to even think of those things!" "Did you get approval from the National Academy of Sciences, the FDA, the AMA, the GOV. HUH?" "Don't fall for THEIR lies!!" "Don't even think of voting for THAT crazy politician!" "This is the way we've done it for decades. Why do you crazies want to undo everything?"
(This is the kind of rhetoric you see and read all over the TV, newspapers, and internet.)
Aaaargh! Enough already!
The real truth has to be discerned by every individual thinking for themselves and coming up with concensus, yet never settling to accept any one idea as absolute.
