I think this excellent thread gets to the core of why you can walk away from the JW's absolutely mentally freely without the slightest bit of guilt, fear or reservation.
It's absolute madness to believe in a global genocidal doomsday god that is going to destroy everyone except JW's and Down's Syndrome people at this apocalyptic event called Armageddon. Madness of the highest order.
And that is what the JW's believe. Press them on it, and they are forced to admit that their theology dictates that all non-JW's will die at Armageddon. If they equivocate and get wishy washy on this most uncomfortable of questions for JW's, then you have your walk-away card!
And it's just as mad to even want to worship such a god.
