Welcome T_A
I don't know how old your ankle biters are but they need to be shielded from the bifurcated mindset of the JWs. Education is a key.
As for the questions about armageddon and the like you'll find your own answers. For me 'armageddon(TM)' is nothing more than fear tool the WBT$ used to frighten people into their cult. Armageddon is hardly even biblical.
The JWs may appear to love your kids but sadly many (not all), have only conditional love for them. When they reach a 'baptismal(TM)' age and they don't get dunked or go pioneering you'll soon see how the attitude turns sour. There is no real love in the congregations......never has been and never will be.
Nice to see more newbies here. It's proof the WBT$ are in decline. People just won't put up with their deception anymore.
Run like the wind away from tha dangers of cult indoctrination.
