The JWs are always grumbling that former JWs are trying to "destroy their faith" and that they have nothing nice to say about the men who write for the Watchtower OR their peculiar teachings.
But then---JWs go to people's homes and try to convince them that they should stop:
praising Jesus,
celebrating or honoring their Lord and Savior on His resurrection or on His birth,
and should not be born again as the scriptures indicate,
and should not have a personal relationship with Him,
do not believe the Holy Spirit dwells within them,
or that Christians should volunteer their time to care for the needs of the poor in their communities.
Thinking on this, I have to wonder just exactly WHO is trying to destroy WHOSE faith?
