Refer your Catholic/Republican neighbors to A Catholic Critique of Jehovah's Witnesses. This is an excellent rebuttal of WT teachings, written for Catholics but useful for anybody facing WT indoctrination.
I started reading the article, but when I got to this point:
That a person with no other equipment than a knowledge of the English
language and a seventeenth century English translation of the Bible in his
hands is qualified to decide all matters of eternal consequence for himself
and the rest of mankind, is the ridiculous conclusion to which the principle
of private judgment can finally be brought.
I stopped here. The writer is no better than the GB, this above quote fits perfectly in any WT; he just believes in something else, and wants to enforce that.
