well....if they didn't immediately suspect you of having an alternative source of information (aka apostasy)....then I would think they would be intimidated as hell LOL
I always felt like an idiot whenever I came across someone in the ministry with a college education in theology or anyone who knew anything about history and the bible.
I kind of relate it to how dumb america is as opposed to other countries. I've spoken with people from all over the world and they always seem to know the current events on a world level, even having more knowledge about what was going on in the states than I ever would. They just always seemed more highly (or simply just better) educated than americans.
So...in my opinion....JW's are the dumb america in the scenario lol
(sorry if I offend anyone by saying americans are dumb, but come on.....what average american knows who the prime minister of Canada even is??...and yes, I'm american and humbly/honestly admit my stupidity lol)
Bottom line tho...I think they would be skeptical of where you got your "information" from....and might even ask you such a question....but I would think that only the most self-righteous "knowledgeable" individual would dare debate anything with you, as I would think most JW's would feel too inadequately qualified to hold their own in such a discussion.
