Welcome to the forum Luke
I must say your walking into a dangerous territory when you fully engage yourself with this highly controlling
religious organization. Right off the bat they instill the notion that anyone not a JWS is deemed bad association or reprehensibly evil,
relatives or not. Then this can go much further toward people who were once JWS and whom posed arguments or complaints about
the organization's doctrines, right up to a total shunning. The JW mantra set up is that if your a JWS your all right, if you are not, you are all wrong
and association with these ones are to be avoided.
And like you said if a person decides later on that they felt better in a different religion other than the JWS , that person would be shunned for
the rest of their lives by all JWS including their own family members. Which to me is against the religious freedom of self expression in most
modernized countries like the US.
The JWs are programed to present all of the good things of the organization up front, ( unconditional love , paradise at hand etc. etc. )
particularly to newly interested ones., t he miserably dark stuff gets shoved off into a corner out of sight in this regard.
