A very small percentage of ex JWs ever post on message boards like this. Of those who do, most come here, post for a while, then move on with their lives. A few stick around for various reasons, maybe they are still pissed off, maybe not, you really can't make generalizations.
Yet it is different than being an ex catholic, because the Catholic religion is not a cult and generally does not damage people in the way that this religion does, since they were not controlled to the same extent as members and are not shunned when they left.
