I find the tread I little bit amusing. JW good points > JW bad points. But your points though are a good comprehensive catalog of JW ideas, you think obviously very positive.
As for argument 1: Character change into good personality?
I was a well-balanced young teenager with positive life attitude,
meriful and loving, non smoker, I had absolutely no destructive side, i liked the bible., was no atheist.
and they made of me an obeying societyman who had to adopted destructive
unloving teachings false hopes, not allowed to go out, to learn dancing, got socially isolated
and sacrificed my higher education, because the world is evil. Then I had part-time job for pioneering, what was very restrictive for my life plan (as male), everything worthless now.
I had to get rid of the character changes they made with me to become happy and free.
The christian god doesnt want to transform us by teachings, but is mercy, love and loving kindness per see,
I think that it was not the teachings that was so much overwhelming, but more the loving kindness of the JW members that convinced me and that I wanted to imitate.
The pionieer spirit for example, i liked it.
The simple life,
the humble attitude.
Human examples I liked to imitate in my teenager area.
But I think that these individuals who were my good examples, were good people already before they became JW and not only by the teachings and charakter change, they were rather hindered to be merciful by the strict organisation rules.
Some JW had always problems because they could not change their character completly and remained drinkers or had other bad behaviours with wife or family (those underdogs in the congregation i did not want to have contact with then). Logically that they faced constant disciplination sessions by the elders.
