Being at the moment the target for a well-intentioned but quite aggressive Jehovah's Witness, I thought I'd gather up a few relevant quotations I've come across over the years.
Don't confuse me with the facts--my mind is already made up. (Source unknown)
People are fully entitled to their own opinions but they are not entitled to their own set of facts.
(Daniel Patrick Moynihan)
Opinionated but uninformed. (two nicely opposed adjectives lifted from a Renée Zellweger interview, modestly used to describe herself)
My personal missionary is actually not "uninformed"--she's just unwilling to look outside the JW canon. Within the canon, her knowledge is--in both senses of the word--exhausting. I'm certainly not interested in converting her to my own brand of secular humanism--she's happy with her convictions and is almost as old as my parents. My geologist husband, however, is far from thrilled about either the Watch Tower bible she sent me or the fact that she refers regularly to such absolutes as a "solid date" for Adam's creation. I find it amusing rather than alarming, but I do see his point in this age of encroaching intelligent design.
